    A3 Scope of Rai lwayGroup Standards

    The overall scope of Railway Group Standards is set out in the Railway GroupStandards Code. The specific scope of this document is set out in Part B2.

    A4 Responsibi li tiesRailway Group Standards are mandatory on all members of the Railway Group*and apply to all relevant activities that fall into the scope of each individualsRailway Safety Case. If any of those activities are performed by a contractor, thecontractors obligation in respect of Railway Group Standards is determined bythe terms of the contract between the respective parties. Where a contractor is aduty holder of a Railway Safety Case then Railway Group Standards applydirectly to the activities described in the Safety Case.

    * The Railway Group comprises Network Rail Infrastructure Limited, Rail Safetyand Standards Board Limited, and the train and station operators who holdrailway safety cases for operation on or related to infrastructure controlled byNetwork Rail Infrastructure Limited.

    Network Rail Infrastructure Limited is also known as Network Rail.

    Rail Safety and Standards Board Limited is also known as RSSB.

    Part BB1 Purpose

    This document mandates the requirements for the design, construction,inspection, maintenance, operation and decommissioning of levelcrossings.

    B2 Application of thisdocument

    B2.1 To whom the requirements applyThis document contains requirements that are applicable to duty holders of theinfrastructure controller category of Railway Safety Case.

    B2.2 Compliance requirementsB2.2.1 Compliance with Parts C to J inclusive, and Appendix 1Except as permitted below, the requirements of Parts C to J inclusive and

    Appendix 1 are mandatory for alterations (as defined in Section B3) to existinglevelcrossings and for new levelcrossings for which Approval in Principle isgiven on or after 5 February 2005.

    Unless required as a result of risk assessment undertaken in accordance withGI/RT7011, action to bring existing levelcrossings into compliance with therequirements of Parts C to J inclusive and Appendix 1 is not required.

    It is permissible for the infrastructure controller to designate specific infrastructureprojects, ongoing when this document comes into force, for which compliancewith the requirements of this document applicable to the design, construction andcommissioning of new or altered infrastructure is not mandatory. Whendesignating such projects, the infrastructure controller shall consider:

    a) its responsibilities under its Railway Safety Case

    b) the stage reached by the project at the time this document comes into force(for example, approval in principle)

    c) whether compliance is necessary to ensure compatibility with other parts ofthe infrastructure

    d) whether compliance is necessary to facilitate safe interworking having regardto changes to related requirements mandated on another Railway Groupmember

    e) the economic impact of compliance, but subject to its Railway Safety Caseobligations.

    Compliance with the requirements of this document relating to inspection,maintenance and in-service condition of infrastructure is mandatory, whether ornot the infrastructure concerned is the subject of a designation, as set out above.

    B2.2.2 Compliance with Part KThe requirements of Part K apply to existing and new levelcrossings.

    The requirements of Part K shall be complied with no later than 5 February 2005,with the exceptions set out below for existing levelcrossings:

    a) Compliance with clause K1.2 (naming of levelcrossings), so far as it can beachieved without conflicting with existing LevelCrossingOrders, is requiredno later than 1 August 2009.

    b) Compliance with clause K9.2 (other engineering work in the vicinity of levelcrossings) is required no later than 6 August 2005.

    c) Compliance with clause K11.1 (requirement to keep records) is required nolater than 6 August 2005.

    B2.2.3 Compliance with Part LThe requirements of Part L apply to levelcrossings when the legal process toclose the crossing(either entirely or to vehicular traffic only), or to alter its status,is complete.

    The requirements of Part L shall be complied with no later than 6 August 2005.

    B2.2.4 General compl iance requirementsUntil the compliance dates, or the date by which compliance is achieved (ifearlier), the applicable requirements of the predecessor documents shall continueto be met (see Part A for details).

    After the compliance dates, or after the date by which compliance is achieved (if

    earlier), Railway Group members shall not deviate from the requirements set outin this document.

    Where it is considered not reasonably practicable to comply with therequirements set out in this document, authorisation not to comply shall besought in accordance with the Railway Group Standards Code.

    Levelcrossings are subject to various legal requirements, including, in somecases, a LevelCrossingOrder, detailing the layout and operation of the particularcrossing. These legal requirements, and the requirements of a LevelCrossingOrder, take precedence over the requirements of this document.

    B2.3 Exclusions from the application of this documentCrossings of the railway that are provided solely for construction or maintenance

    purposes on a temporary basis are excluded from the scope of this document.

    B2.4 Related requirements in other documentsManagement requirements for the control of vegetation on Network Railcontrolled infrastructure are set out in GC/RT5202.

    Design requirements for the avoidance of direct contact between persons and liveparts of electrification equipment are set out in GE/RT8025. These includerequirements for conductor rail layout at levelcrossings and the minimum heightof the lowest live part of the overhead line equipment (OLE) above the surface oflevelcrossings.

    Management requirements for the control of unauthorised access to Network Railcontrolled infrastructure are set out in GE/RT8063.

    Requirements for the acceptance of systems, equipment and materials for use onNetwork Rail controlled infrastructure are set out in GI/RT7002.

    Requirements for the provision of new levelcrossings and the risk assessmentand risk review of existing levelcrossings are set out in GI/RT7011. GI/RT7011also sets out requirements for selecting types of levelcrossings for use inparticular circumstances, and requirements for levelcrossings to be closed incertain circumstances.

    The arrangements for the management and specification of lineside operationalsafety signs in order to provide consistency of form and presentation throughoutthe network are set out in GI/RT7033. This standard includes signs required atlevelcrossings.

    Particular requirements for the testing and commissioning of signalling andoperational telecommunications equipment which is to be used as part ofNetwork Rail controlled infrastructure are set out in GK/RT0209.

    B5 Introduction:

    Al terations to levelcrossings

    This section is a descriptive introduction to GI/RT7012. It does not containmandatory requirements, but draws attention to an important point.

    It is the intention of this document that alterations to levelcrossings contribute toimproving safety. This should however be achieved without imposingunreasonable costs on the industry.

    Alteration of a levelcrossingis therefore defined (in section B3) as 'thesubstantial renewal of all or part of an existing levelcrossing, which provides areasonable opportunity to significantly improve the safety performance of theelement subject to alteration'.

    It is important to understand that the requirements of this document do not applysimply because an alteration is made to part of a levelcrossing. Therequirements are only mandatory where the alterations provide a reasonableopportunity for achieving compliance. The following examples illustrate how therequirements of this document apply:

    a) If the signs at a levelcrossingare replaced, they are to meet therequirements of section C4, but there is no requirement to carry outadditional works at the levelcrossing.

    b) If the gateon one side of a levelcrossingis replaced because it is defective,the gatethat is being replaced is to meet the requirements of section C3, butthere is no mandatory requirement to replace the gateon the other side ofthe crossing, unless this would result in different gatewidths.

    c) If signalling alterations are carried out which involve the repositioning ofsignals to bring them into compliance with clause E6.1, there is norequirement to carry out other works at the levelcrossing.

    Part C

    Levelcrossingcontrol measuresC1 Minimum

    combinations of levelcrossingcontrol

    measuresC1.1 Requirements of GI/RT7011Minimum combinations of levelcrossingcontrol measures are set out inGI/RT7011(in this context, a control measure is an item required for the safetyof crossingusers). The required control measures include:

    a) barriers (lifting barriers, gates and stiles)

    b) fixed signs

    c) telephones to the signaller or crossingkeeper

    d) active visible warnings

    e) active audible warnings.

    Part C of this document sets out the requirements for the control measures listedabove.

    C2 Lift ing barriersC2.1 Barriercrossings worked by the userWhere barriercrossings are worked by the user, a single lifting barriershall be

    provided on each side of the railway, which when lowered shall fully close thecrossingapproaches from the railway.

    To prevent vehicles becoming trapped, the clearance between barrierposts shallbe the same at both sides of the railway to ensure that ease of entry and exit isconsistent. This shall usually provide a minimum clearance of 3.0 m and amaximum of 5.0 m.

    In exceptional circumstances, and with the prior approval of HM RailwayInspectorate, it is permissible to provide a larger clearance.

    Controls for the user shall be provided on each side of the railway. It shall bepossible to raise and lower both barriers from any control point. Both barriersshall operate simultaneously.

    Operating instructions for the user shall be clearly displayed adjacent to eachcontrol point.

    The agreement of users of the crossingto lock the barriers shall be sought. Iflocking of the barriers is agreed, any failure to do so shall be followed up with theusers.

    Where there are footpath or bridleway rights over a user-worked crossing,separate facilities applicable to the appropriate status shall be provided, forexample, by providing wicket gates or stiles in addition to barriers.

    The default position for barriers at user-worked crossings shall be lowered.

    C2.2 Barriercrossings worked by an automatic control system

    Where barriercrossings are worked by an automatic control system, for example,automatic half-barriercrossings or automatic barriercrossings locally monitored,the barriers shall extend across only the left-hand side of the carriageway andfootway when lowered.

    Barriers shall be pivoted on the left-hand side of the roadon each approach.

    The default position for barriers at automatic barriercrossings shall be raised.

    C2.3 Barriercrossings worked by train crew, signallers or crossingkeepersThe barriers when lowered shall fully close the carriageway and footway on bothsides of the railway.

    Two arrangements are permissible:

    a) a single barrieron each side of the railway, each barrierextending across thefull width of the carriageway and footways, and

    b) two barriers on each side of the railway, each barrierextending to thecentreline of the carriageway.

    If automatic lowering is employed, two barriers on each side of the railway shallbe provided.

    Where two barriers are provided on each approach, the barriercovering the left-hand side of the roadshall be lowered first. All barriers shall rise together.

    Where single barriers are provided, they shall be pivoted on the left-hand side ofthe roadunless site constraints prevent this.

    The default position for barriers at crossings worked by train crew, signallers orcrossingkeepers shall be raised. In exceptional circumstances for barriers atcrossings worked by signallers or crossingkeepers, it is permissible for thedefault position for the barriers to be lowered.

    Where a crossingis worked by a signaller or crossingkeeper from a control pointwhich is more than 50 m from the crossing, or where the view of the crossingisinadequate, supervision by CCTV shall be provided. The CCTV shall provide agood view of the whole crossingarea, including the stop lines.

    Where supervision is not by means of CCTV, the person operating the barriersshall have a clear view of approaching roadtraffic and the whole crossingarea.

    C2.4 Visibility of barriers to usersAlternate red and white bands, nominally 600 mm long, shall be provided to thefull depth on both sides of the barrierboom. A strip of retro-reflective material notless than 50 mm deep shall be provided along the full length of each band onboth sides of the barrier.

    Each barrierboom shall be fitted with red lights visible in each direction along thecarriageway where this is necessary to ensure visibility. One light shall be within150 mm of the barriertip. The lights shall be illuminated at all times when thebarriers are not in the fully raised position.

    It is permissible to omit barrierlights at user-worked barriercrossings where nopower supply is available.

    C2.5 Provision of skirts at crossings with full barriersAt any levelcrossingequipped with full barriers, skirts shall be fitted where eitherthere is a significant risk of pedestrians deliberately passing under the loweredbarriers or where herded animals are regularly taken over the crossingon thehoof.

    Where provided, skirts shall be of light colour, light construction and shall fence inthe space between the lowered barriers and the roadsurface.

    C2.6 Barriers displaced by collision

    Lifting barriers shall be designed such that when displaced by a collision with aroadvehicle, the boom separates from the barriermechanism.

    C3 Gates and sti lesC3.1 Gated cross ings worked by the userA single gateshall be provided on both sides of the line. Exceptionally, and withthe prior approval of HM Railway Inspectorate, it is permissible to provide doublegates where site constraints make this necessary.

    The gates shall be arranged so that it is not possible to open the gates towardsthe railway or move them into a position where they obstruct the passage oftrains.

    The gates shall be sited as close to the track as is practicable, but not less than2.0 m from the nearest running rail. In determining the position of the gates,consideration shall be given to the effect on any provision made for safe accessalong the railway, for example, cess walkways or continuous positions of safety.

    To prevent vehicles becoming trapped, the clearance between gateposts shall bethe same on both sides of the railway to ensure that ease of entry and exit isconsistent. This shall provide a minimum width of 3.0 m and a maximum of5.0 m.

    Means shall be available to secure both of the gates in both closed and openpositions.

    The agreement of authorised users of the crossingto lock the gates shall besought. If locking of the gates is agreed, any failure to do so shall be followed upwith the users.

    Where there are footpath or bridleway rights over a user-worked crossing,separate facilities applicable to the appropriate status shall be provided, forexample, by providing wicket gates or stiles in addition to gates.

    The default position for gates at user-worked crossings shall be closed.

    C3.2 Gated crossings worked by train crew, signallers or crossingkeepersAt gated crossings operated by railway staff, the gates shall usually be arrangedsuch that when opened to the roadthey close across the railway. The gates shallcomplete the fencing of the railway when closed across either the roador therailway.

    Where site conditions dictate that the gates open away from the railway, a cattle-

    cum-trespass guard shall be provided.

    There shall be a means of securely retaining the gates in both open and closedpositions. They shall be lockable in either position.

    The default position for gated crossings worked by signallers or crossingkeepersshall be closed across the road, except where formal authorisation has beenobtained from HM Railway Inspectorate for the default position to be closedacross the railway.

    The default position for gated crossings worked by train crew shall be closedacross the railway.

    C3.3 Separate wicket gates for pedestrians at gated vehicu lar crossingsIt is permissible to provide separate wicket gates for pedestrians at gated

    vehicular crossings.

    Crossings equipped with white lights are not suitable for use by members of thepublic (see clause C6.2), unless accompanied by railway staff.

    It is permissible for the active visible warning to be provided by red/green lights atcrossings for use by railway staff, provided these are not located at stations.

    C6.2 Active visible warnings at crossings worked by users (other thanrailway staff)Where active visible warnings are required at crossings worked by users,(including station foot crossings, footpath crossings, bridleway crossings anduser-worked crossings) red/green lights, as specified in the Private Crossings(Signs and Barriers) Regulations 1996, shall be provided on each side of therailway, facing outwards from the railway towards approaching users.

    C6.3 Active visible warnings at crossings on public roadsThe requirements for roadtraffic light signals are set out in the Traffic Signs

    Regulations and General Directions 2002.

    All roadtraffic light signalunits at a levelcrossingshall be of a similar type andshall produce outputs of similar light intensity.

    Where it is identified that significant differences in the characteristics of roadtraffic light signals at nearby crossings could give rise to a risk of roadusersfailing to heed them, light signals of a similar type shall be provided at allcrossings within the area where it is considered that such a risk could arise.

    At automatic crossings, separate light signals for pedestrians (as set out in theTraffic Signs Regulations and General Directions 2002) shall also be providedwhere a requirement for such signals is identified because of high pedestrianusage or regular use by vulnerable groups of pedestrians.

    C6.4 Requirements for the control of active visible warningsParticular requirements for the control of active visible warnings are set out inPart E.

    C7 Active audiblewarnings

    C7.1 General requirements for active audible warningsThe requirements to provide active audible warnings are set out in GI/RT7011.

    At levelcrossings with full barriers controlled by railway staff, the audible warningshall commence when the roadtraffic light signals are illuminated at thecommencement of the barrierlowering sequence, and shall cease when allbarriers are fully lowered.

    At all other types of crossingprovided with active audible warnings, the audiblewarning shall commence at the initiation of the warning sequence and shallcontinue until all approaching trains have passed clear of the crossing. At suchcrossings where a second train approaches the crossingduring the warningperiod for the first train, the audible warning shall change distinctively as soon asthe first train arrives at the crossing.

    C7.2 Characteristics of sound to be producedWhen the levelcrossingoperating cycle is initiated, the audible warning deviceshall emit a continuous sound comprising repetition of two alternating tones. Thetwo alternating tones shall have frequencies of 800 Hz 1% and1000 Hz 1%, and shall be of equal duration. The tonal sequence shall repeatapproximately every 0.5 second.

    When a distinctive tone is required to give warning of a second train approachingthe crossing, the tonal sequence shall alternate at an increased rate, repeatingapproximately every 0.25 second.

    Telephone systems at levelcrossingsD1 General

    requirements for levelcrossingtelephone

    systemsD1.1 Design principles for telephone systemsLevelcrossingtelephones systems shall be designed to ensure that:

    a) the crossinguser has a simple means of setting up a call, for example, byoperating a single button

    b) the crossinguser, when initiating a call, receives a ring tone if the call is

    successful in ringing in the designated control or supervising point

    c) the presence of incoming calls is always indicated to the signaller or crossingkeeper

    d) calls from telephones available to a crossinguser are routed only to thedesignated control or supervising point

    e) the control or supervising point has the facility to initiate a call to the levelcrossing.

    D1.2 Equipment at the control or supervising pointThe equipment at the designated control or supervising point shall:

    a) allow calls to be made to, or received from, all levelcrossings for which it isresponsible and which have telephones provided

    b) provide an audible indication of incoming calls

    c) provide a visual indication of the status of the calling circuit (unless individualtelephones are used)

    d) be labelled or displayed such that the associated crossingor group ofcrossings is clearly identifiable to a user making or receiving a call

    e) be arranged logically in relation to the signalling control equipment ordiagram

    f) ensure that the signaller is only able to handle one call from a levelcrossing

    at a time.

    So long as the requirements of this section and, where relevant, section D6 arecomplied with, it is permissible to connect levelcrossingcircuits to a telephoneconcentrator, a key system or separate telephones.

    If the signaller or crossingkeeper has to go outside the control or supervisingpoint in the course of normal duties, consideration shall be given to making thecalling signal(indicating an incoming call from the levelcrossing) audiblewherever the signaller needs to go.

    D1.3 Levelcrossingcircui ts provided via a telephone exchangeAt crossings, other than those worked by an automatic control system monitoredby a signaller or crossingkeeper, it is permissible to provide levelcrossingcircuits via a telephone exchange or electronic switch and with auto-phonesinstalled at the crossing.

    A separate exchange line shall usually be provided in the control or supervisingpoint for each levelcrossingfitted with auto phones. Where there are multiplecrossings in a block or signalsection, it is permissible to set up the telephones atall of them to ring the same extension at the control or supervising point, providedthat a hunt group is established. Sufficient lines shall be provided on the huntgroup to ensure that a caller does not receive the engaged tone under theexpected levels of crossingusage.

    It shall be simple to set up a call from the control or supervising point to anycrossingand consideration shall be given to minimising the likelihood ofmisdialling. Telephone lines provided for this purpose shall not be used forgeneral purposes unless calls from levelcrossings can be prioritised to avoidreceiving an engaged tone.

    D1.4 Closure of the control or supervising pointIf it is possible for the control or supervising point to close while the line remains

    open to railway traffic, facilities shall be provided to transfer calls from any levelcrossingphone to the control point taking over responsibility. The transfer shallbe achieved using the closing switch used to transfer signalling controls (seeclause E4.5.2).

    When a control or supervising point closes and the line is closed to railway traffic,consideration shall be given to providing an automatic announcing facility to tellcrossingusers that the line is closed and that it is safe to cross. If provided, thisfacility shall be activated by an absence switch interlocked with the signals insuch a way that the signals cannot be cleared until the switch is returned to itsnormal position.

    D1.5 Types of telephones for use at levelcrossingsTelephones at crossings shall be one of the following types:

    a) a direct line with either lift-to-call or press-to-call operation

    b) a levelcrossingtelephone system, such as the Public Emergency TelephoneSystem (PETS)

    c) an auto-phone capable of dialling only one number, either by programming ofthe telephone or by configuration of the exchange.

    Telephones for crossingusers at a particular crossingshall all be of the sameappearance and operate in the same way.

    The telephone equipment shall be suitable for its intended use and haveadequate resistance to the effects of foreseeable weather and vandalism.Special precautions shall be taken in locations where specific problems are

    known, for example, sea spray.

    D1.6 Telephone circu itsD1.6.1 Number of circuitsAll telephones at a crossingshall usually share a single circuit back to the controlor supervising point. Separate circuits are permissible where all the followingconditions can be met:

    a) all other requirements for the telephone operation and monitoring can becomplied with

    b) the risk associated with a crossinguser having to cross the l ine to answer acall is considered

    c) the signaller or crossingkeepers indications and call facilities areunambiguous.

    b) a circuit partly or wholly provided by a public network, including a radiosystem.

    A network termination point shall be provided to define any point whereresponsibility for maintenance changes. Where possible, the network terminationpoint shall be positioned where access to it can be obtained without the personrequiring personal track safety competence or supervision.

    D1.7 AvailabilityThe system design and the maintenance regime shall be determined to provide

    availability appropriate to the levelof risk associated with the equipment failure.

    Power supplies for levelcrossingcommunications shall be designed to ensurethat voice communications can continue for a minimum of 12 hours after the lossof the primary power supply.

    Loss of a primary power supply provided by the infrastructure controller to a levelcrossingtelephone system shall be indicated at the control or supervising point.

    D2 Positioning oftelephones

    D2.1 Minimum requirementsWhere telephones are provided for the use of crossingusers, there shall be atleast one telephone on each side of the railway line. The telephones shall be

    clearly visible from the crossingarea and from any signadvising users totelephone.

    Telephones shall be positioned such that the user is in a position of safety fromboth roadand rail vehicles. Where there is a risk that the user could move out ofthe position of safety whilst using the telephone, consideration shall be given tothe provision of a physical barrier.

    Where possible, telephones shall be located to permit the user to operate thetelephone whilst standing upright. The height of telephones shall be chosen topermit all users to make calls and read any information provided. It is permissibleto assume that young children will be accompanied but consideration shall begiven to the possibility of wheelchair users needing access.

    A level, stable surface shall be provided for the user to stand on whilst using thetelephone.

    At levelcrossings with roadtraffic light signals, telephones shall be positionedadjacent to the right-hand side light units.

    At other levelcrossings, telephones shall be positioned adjacent to the point ofaccess to the railway.

    D2.2 Addit ional requirementsWhere telephones are provided on bridleway crossings with facilities for riders toopen gates without dismounting, consideration shall be given to providingadditional telephones useable by a mounted rider.

    Where crossings are provided with a local control unit (see section E11), atelephone shall be accessible by the person operating the controls. A dedicatedtelephone shall be provided if none of the telephones provided for the crossinguser are within reach.

    E1.2 Control of white light indicatorsThe white light indicators shall be illuminated when it is safe to cross, and shall beautomatically extinguished on the approach of a train.

    The warning shall be initiated automatically by the approaching train. The

    arrangements shall ensure that no train arrives at the crossingin less than thespecified minimum period after the initiation of the warning sequence, and thestrike-in points shall be positioned to ensure this, taking into account any timedelays in the operation of the equipment. The warning shall cease as soon as allapproaching trains have passed clear of the crossing.

    E1.3 Warning timesThe controls shall ensure that the warning time is sufficient for a user to traversethe crossingfrom the decision point and reach a place of safety at least10 seconds before the arrival of a train. Determination of the minimum warningtime shall take into account:

    a) the number of tracks to be crossed

    b) the approach speed of trains

    c) the nature of the crossinguser, for example, pedestrians, users of barrows orother wheeled vehicles.

    Where there is a stop signalbetween the strike-in point and the crossing, it ispermissible to inhibit the warning when the signalis at danger and free ofapproach locking, in order to avoid excessive warning times. Where a trainaccelerating from the signalwould be able to reach the crossingin less than theminimum warning time, clearance of the signalshall be controlled in accordancewith clause E9.3 to ensure that the minimum warning time will not be reduced.

    E1.4 Train detectionTrain detection systems shall be designed to ensure:

    a) immediate detection of the first vehicle of a train as soon as it reaches thestrike-in point

    b) reliable detection of all trains, taking into account possible rail headcontamination

    c) detection of the direction of the train movement (see section E8).

The warning shall cease as soon as allapproaching trains have passed clear of the crossing.

    E2.3 Warning timesThe minimum warning time for a crossingequipped with red/green lights, from theillumination of the red light to the arrival of the train, shall not be less than theminimum warning time set out in the table below for the type of crossingconcerned. This minimum warning time shall be increased, where necessary, toensure that it is at least five seconds longer than the time required for anyexpected users to traverse the crossing, from the decision point to a point atwhich they are completely clear of the railway on the far side of the crossing. Inthis case, the decision point is a point at which the crossinguser can see the red

    and green lights before starting to cross.

    A drivers levelcrossingindicator (in accordance with GK/RT0031) shall beprovided for the train driver on each rail approach to the crossing. The crossingindicator shall be positioned approximately 5 m before the crossing.

    Where there is a running signalin close proximity to the crossing, the controlsshall be arranged to avoid any possibility of confusion between indications givenby the signaland by the drivers levelcrossingindicator. If necessary, in order toachieve this, it is permissible not to provide a drivers levelcrossingindicator; inthis case the proving of the correct operation of the crossingshall be incorporatedinto the controls of the signalproceed aspect, as set out in clause E3.6.

    E3.2 Train detectionTrain detection systems shall be designed to ensure:

    a) immediate detection of the first vehicle of a train as soon as it reaches the

    strike-in point

    b) reliable detection of all trains, taking into account possible rail headcontamination

    c) detection of the direction of the train movement.

    Where the train detection system is susceptible to false operation by roadvehicles, the system shall be designed to prevent incorrect initiation of the

    crossingclosure sequence resulting from the passage of roadvehicles.

    E3.3 Operational sequencesE3.3.1 Initiation of crossingclosureThe operation of the levelcrossingshall be initiated by detection of anapproaching train, except as set out in clause E3.5.

    The requirements for the crossingclosure sequence are set out in clause E7.1.The barriers shall take not more than 10 seconds, from the time when theycommence to lower, to reach the fully lowered position. The train shall arrive atthe crossingnot less than 27 seconds after commencement of the closuresequence.

    When the crossingis longer than 15 m, the minimum warning time shall beincreased from 27 seconds by one second for every additional 3 m of crossinglength or part thereof.

    On double-track lines, the arrangements for closing the crossingshall ensure thatit remains closed to roadtraffic if the required minimum roadopen time cannot beensured between trains. In order to achieve this, the crossingshall be preventedfrom opening following the passage of one train if another train is approaching thecrossingand will arrive within 10 seconds at the point at which the crossingclosure needs to be initiated. The delay of 10 seconds allows for the minimumroadopen time plus the time required to allow the barriers to rise to the positionat which the roadtraffic light signals are extinguished.

    If a separate another train coming strike-in point is not provided, the strike-inpoint shall be positioned at a distance equivalent to 10 seconds, for a trainrunning at maximum permissible speed, before reaching the point where the

    crossingclosure needs to be initiated. If the crossingis already closed when atrain reaches the strike-in point, it shall remain closed; if the crossingis open, theclosure sequence shall be initiated after a delay of 10 seconds.
