7 Railway Group Standard Page 5 of 17 B1 Purpose B2 Application of this document Part B This document defines the requirements for positioning lineside telephones, in relation to other items of infrastructure and defines the labels and signs required in association with such telephones. B2.1 To whom and to what the requirements apply This document contains requirements that are applicable to duty holders of the following categories of Railway Safety Case: a) infrastructure controller b) station operator The requirements of this document apply to all lineside telephones or plug points that can be used as a lineside telephone (other than those required at level crossings) as defined in section B3. Under the Railways (Safety Case) Regulations 2000, the duty holder at a station (as defined in those Regulations) is responsible for ensuring that the requirements of Railway Group Standards are complied with. At a station, contractual arrangements (including a lease) do not of themselves relieve the duty holder of his obligations under those Regulations. Requirements relating to the provision, positioning and labelling of telephones associated with a level crossing are contained in GK/RT0183. B2.2 Compliance requirements B2.2.1 Infrastructure controller The requirements of this document apply to the infrastructure controller for all lineside telephones designated as signal post telephones (SPTs), and for all other lineside telephones and plug points that are not in an area for which a station operator is responsible (see section B2.2.2). B2.2.2 Station operator The requirements of this document apply to station operators for all lineside telephones that are located in areas for which they are responsible, other than those designated as signal post telephones (SPTs). B2.2.3 General compliance requirements The provisions in this document are to be complied with from 6 April 2002 for any new lineside circuits and for any signal post telephone associated with a new or relocated signal. Where Approval in Principle for signalling alterations or for concentrator/exchange renewal is given before 6 April 2002, but the infrastructure has not yet been brought into service, the works shall be reviewed and, where reasonably practicable, brought into compliance with the requirements of this document. As from 6 April 2002, any existing lineside telephone that requires re-labelling or replacement, shall be labelled in accordance with the requirements of this document. All lineside telephones, whether new or existing, shall be labelled in accordance with the requirements of this document by 1 September The requirements of sections B4.3 and B12 shall be complied with from 6 April 2002 in respect of all new and existing lineside telephones.

8 Railway Group Standard Page 6 of 17 Uncontrolled When Printed Until the compliance dates, or the date by which compliance is achieved (if earlier), the applicable requirements of the predecessor documents shall continue to be met (see Part A for details). After the compliance date, or after the date by which compliance is achieved (if earlier), Railway Group members shall not deviate from the requirements set out in this document. Where it is considered not reasonably practicable, to comply with the requirements set out in this document, authorisation not to comply shall be sought in accordance with GA/RT6001, GA/RT6004 or GA/RT6006. B3 Definitions Direct line A telephone that only connects the user to one location, for example a signal box or an electrical control room. Identification label Any sign or label fitted on an external surface of the telephone housing, provided to help locate the telephone and to identify its function. Information label A label, usually fitted on an internal surface of a telephone housing, providing essential information to the user. Limited clearance SPT A signal post telephone (SPT) positioned such that the user is not in a position of safety. Lineside telephone Any fixed telephone installed on or about the railway and required for the day-today running of the railway or specifically identified for use in an emergency on the railway. This includes both telephones that are located at, or accessible from, the lineside, and also telephones in railway offices that are accessed directly from station platforms. Position of safety A position where people can stand safely while trains pass, meeting the requirements of GC/RT5203. Platform starting signal A signal that must be displaying a proceed aspect before a train can be dispatched from a platform (see GK/RT0037 for further details). Plug point A socket provided to allow telephones fitted with a suitable plug to be used as a lineside telephone. Signal element Any part of a signal that can present signalling information to a driver (see GK/RT0037 for further details). Signal post telephone (SPT) A direct line telephone provided adjacent to a signal and linked to the controlling signal box, whose primary purpose is to allow safety related instructions to be passed between the signaller and the driver of a train. Telephone number plate A plate displaying the telephone number for the controlling signaller box to be dialled by a driver when contacting the signaller using National Radio Network (NRN) equipment. 6 RAILWAY SAFETY

9 Railway Group Standard Page 7 of 17 B4 General requirements for lineside telephones B4.1 Provision of lineside telephones B4.1.1 Requirements for the provision of lineside telephones The following Railway Group Standards mandate the provision of lineside telephones: a) GK/RT0041 SPTs in track circuit areas. b) GK/RT0042 SPTs in absolute block areas. c) GK/RT0051 SPTs in single lines. d) GK/RT0054 Lineside telephones on radio electronic token block RETB) lines. e) GK/RT00061 at ground frames and shunters releases. f) GK/RT0183 at level crossings. g) GK/RT0193 Lineside communications with electrical control rooms. Lineside telephones provided in addition to those required by the documents listed above shall also comply with the requirements of this standard. B4.1.2 Association with items of infrastructure associated with a particular item of infrastructure (eg a signal or points) shall usually be positioned such that the association is readily apparent. If necessary, signs shall be provided on or adjacent to the item of infrastructure to indicate where the associated telephone is located. Lineside telephones and any supporting structure shall be positioned to comply with the requirements for minimum structural clearances. (Refer to GE/RT8029). B4.1.3 Safety of user Except where permitted by section B5.1.4, telephones shall be positioned such that the user is in a position of safety. Where there is a risk that the user could move out of the position of safety whilst using the telephone, consideration shall be given to the provision of a physical barrier. B4.1.4 Physical considerations shall usually be located to permit the user to operate the telephone whilst standing upright. A level, stable surface shall be provided for the user to stand on whilst using the telephone. B4.2 Identification and information labels All lineside telephones shall have an identification label and an information label. The grid reference of the telephone, accurate to within 100 m (eg SW ), shall be displayed on the information label unless an alternative location reference, agreed between the responsible Railway Group member and the emergency services, is provided. Where lineside plug points are provided as a means of communication, the labelling requirements shall be the same as for fixed telephones. The information label shall be positioned so as to be readable by a user. There shall also be a clearly visible label stating, plug point. Identification labels are defined in GK/RT0033. RAILWAY SAFETY 7

10 Railway Group Standard Page 8 of 17 Uncontrolled When Printed B5 Signal post telephones B4.3 not in service Lineside telephones that have been installed but not brought into service, or have been taken out of service but not removed, shall be indicated in such a way as to inform any potential user that the telephone is not in service. Lineside telephones that have become faulty shall be similarly labelled, if the telephone is not successfully returned to operation during the first attendance on site of a repair technician. B5.1 Positioning B5.1.1 Visibility of associated signal SPTs shall be positioned such that a person using the telephone can readily see all elements of the signal and associated identification plate or sign. B5.1.2 Distance between SPT and signal Consideration shall be given to placing the SPT at a position further from the signal than the nearest point to the signal meeting the requirement of section B In this case, the position of the SPT shall be selected to suit the position where trains come to a stand when the signal is at red. The infrastructure controller shall agree this position with all relevant train operating companies. See Figure USUAL POSITION OF SPT TO ALLOW USER TO SEE ALL ELEMENTS OF THE SIGNAL (CLAUSE 5.1.1) ALTERNATIVE POSITION OF SPT WHERE TRAINS COME TO A STAND WHEN THE SIGNAL IS AT RED (CLAUSE 5.1.2) Figure Requirements for the provision of walkways on the approach to SPTs are set out in GC/RT5203. Requirements for providing protective guard boarding around conductor rails alongside SPTs are set out in GE/RT8025. B5.1.3 Other positioning requirements SPTs shall usually be positioned on the same side of the line as the associated signal. It is permissible to position the SPT on the opposite side if by doing so it reduces the personal risk to drivers using it. (See section B5.4.1 for additional signs required in this case). Where a platform starting signal is not located on the platform, consideration shall be given to providing a second telephone, on the platform, to avoid the need for the driver to use the cess to gain access to the SPT. Where physical restrictions such as retaining walls or tunnels exist, particular consideration shall be given to the accessibility of the SPT. It is permissible for such SPTs to be positioned so as to be accessible without leaving the train. In all cases a person standing at the trackside shall be able to access the SPT or a parallel telephone provided specifically to comply with this section. B5.1.4 Limited clearance SPT It is permissible to place an SPT such that the user is not in a position of safety where it is not reasonably practicable to comply with the requirements of 8 RAILWAY SAFETY

11 Railway Group Standard Page 9 of 17 section For each such SPT, records shall be kept of the justification for not achieving a position of safety. Such SPTs are designated limited clearance SPTs. See sections B5.3 and B5.4 for requirements for additional information, labels and signs associated with limited clearance SPTs. GO/RT3000 provides instructions as to how a limited clearance SPT is used. B5.1.5 Non-provision of an SPT An SPT need not be provided if all of the following conditions apply: a) the SPT is positioned between two lines, and the user is not in a position of safety relative to the line that the SPT does not apply to b) radio coverage for train radio systems is considered adequate c) another fixed telephone is positioned nearby which can be used to contact the signaller in an emergency. B5.2 Information labels The information label shall provide: a) instructions on how to use the telephone b) the name of the control point (signal box) c) the signal number d) the location reference (see section B4.2) e) the phonetic alphabet. B5.3 Identification labels All SPTs shall display the Signal Post Telephone sign, as illustrated in GK/RT0033. See also Figure A1 in the appendix of this standard. Where the driver is required to contact the signaller within a time period other than that laid down in GO/RT3000, a number shall be superimposed on the Signal Post Telephone sign to indicate the response required, see GK/RT0033 for details. In the case of limited clearance SPTs, a limited clearance sign shall be displayed below the Signal Post Telephone sign, as illustrated in GK/RT0033. See also Figures A2 and A3 in the appendix of this standard. B5.4 Requirements for additional signs B5.4.1 SPT fitted on the opposite side of the line Where the SPT is on the opposite side of the line from the signal (section B5.1.3), an additional Signal Post Telephone sign shall be fitted on the same side as the signal, positioned where the SPT would otherwise be fitted, together with an arrow pointing to the SPT. B5.4.2 SPT users not clear of an adjacent track Where an SPT is positioned between two lines and the user is not in a position of safety relative to the line that the SPT does not apply to, a white diamond sign bearing a black letter X is required and shall be fitted close to the signal number plate. A miniature white diamond bearing a black letter X shall also be fitted below the SPT (see Figure A3). Where the NRN system is in use, a telephone number plate shall also be fitted close to the signal number plate. RAILWAY SAFETY 9

12 Railway Group Standard Page 10 of 17 Uncontrolled When Printed B5.4.3 Omitted SPT If an SPT is to be omitted and the train s presence is indicated to the signaller by track circuit or other train detection systems, a plain white diamond sign shall be fitted close to the signal number plate (see Figure A4). A telephone number plate shall be fitted close to the signal number plate. B6 Other direct lines to signal boxes B6.1 Positioning Where a user is required to talk to the signaller whilst operating signalling equipment (eg removing a token or pressing a plunger), the telephone shall be positioned such that the user can continue to speak and listen whilst carrying out the specific task required. B6.2 Information labels The information label shall provide: a) instructions on how to use the telephone b) the name of the control point c) the location of the telephone d) the location reference (see section B4.2) e) the phonetic alphabet. B6.3 Identification labels All telephones that have a direct line to the signal box or crossing box but are not SPTs shall have a Lineside Telephone sign fitted. (See GK/RT0033). Where direct line telephones are located in offices or platform kiosks it is permissible for the Lineside Telephone sign to be substituted by other labelling that clearly identifies the telephone as a direct line to the signal box and not for 999 use. B7 Direct lines to electrical control rooms B7.1 Information labels The information label shall provide: a) information on how to use the telephone b) the name of the electrical control room c) the location of the telephone d) the location reference (see section B4.2) e) the phonetic alphabet. B7.2 Identification labels on direct lines to electrical control rooms shall have an Electrification Telephone sign fitted. (See GK/RT0033). 10 RAILWAY SAFETY

13 Railway Group Standard Page 11 of 17 B8 with dialling facilities B8.1 Information labels The information label shall provide: a) instructions on how to use the telephone b) the telephone s extension number on the relevant network c) contact telephone numbers, including short code facilities, for relevant control points (eg signal box, electrical control room or emergency services) d) details of how to report a telephone fault e) the location of the telephone f) the location reference (see section B4.2) g) the phonetic alphabet. B8.2 Identification labels with dialling facilities shall usually have a black handset symbol on a white background fitted (see GK/RT0033). designated as an emergency telephone shall instead have a white on green handset label bearing the words Emergency Telephone. If it is not possible to contact the emergency services from the telephone it shall also be signed Not for 999. B8.3 Dial telephones in railway offices accessed from platforms If it is not possible to contact the emergency services from the telephone it shall also be signed Not for 999. Where it is not practicable to attach an information label to the telephone, it is permissible for the information to be displayed clearly nearby. B9 Construction of telephone units The telephone equipment shall resist the effects of anticipated weather and vandalism. Special precautions shall be taken in locations where specific problems are known, for example sea spray. Specifying a maximum length of handset cord can contribute to controlling the risk of a user moving out of a position of safety. The handset cord length shall be specified if this is intended as a risk control measure. B10 Positioning process B10.1 Site assessment To ensure adequate consideration of the risk to users, a site assessment shall be held to ensure that location-specific factors are taken into consideration when deciding the position of each lineside telephone. These factors shall include, but are not limited to: a) users of the telephone b) calling facilities required c) permissible speed d) ground conditions RAILWAY SAFETY 11

14 Railway Group Standard Page 12 of 17 Uncontrolled When Printed e) particular risks from vandalism f) particular environmental hazards to the user or the equipment g) proximity to other infrastructure controller s railways. B10.2 Details to be agreed The site assessment shall agree and record: a) the lateral and longitudinal position of the telephone (eg in relation to the running edge of the nearest rail and the signal) b) the mounting arrangement c) whether the ground requires making up, or a walkway, platform or barrier needs to be provided (section B4.1.4) d) whether conductor rail boarding is required e) vandal proofing and handset cord length required (section B9) f) requirements for additional signs for SPTs (section B5.4) g) any prohibition of handsignalman working When associated with signal sighting, these details shall be provided in the signal sighting documentation. B10.3 Attendance at site assessment The responsible Railway Group member shall arrange suitable attendance for the site assessment. The following organisations shall be invited: a) train operators, where train operating staff are required to use the telephone b) station operators, where telephones are to be positioned on platforms c) other infrastructure controllers, where no physical boundary exists to separate railway operations. The positioning of SPTs shall be undertaken by a signal sighting committee when the associated signal is new or altered. Requirements for signal sighting committees are set out in GK/RT0037. B11 Records B11.1 Minimum information to be retained The responsible Railway Group member shall maintain a record for each telephone. It shall contain, as a minimum: a) details of the telephone s position relative to the infrastructure b) any special safety measures provided, for example barriers, conductor rail boarding or ground preparation c) details of information on information labels d) identification labels provided e) any specific construction details required to control an identified risk. The infrastructure controller shall ensure that any requirements for signs to be fixed to signal structures are recorded on the signal sighting details for the signal affected. 12 RAILWAY SAFETY

15 Railway Group Standard Page 13 of 17 Requirements for the management of safety-related records of elements of the infrastructure are set out in GI/RT7001. B11.2 Availability of information Records shall be accessible for the purposes of: a) investigating complaints b) planning alterations to telephones c) maintenance checks. B12 Routine inspections All telephones shall be inspected at regular intervals to ensure that: a) the telephone functions correctly b) the identification labels are displayed as listed in the records c) the information label is clear and as listed in the records. The frequency of these inspections shall be determined by the responsible Railway Group member, having due consideration for the consequences of the telephone being defective or incorrectly labelled when required to be used. If any information is found to be out of date, arrangements shall be made to have the details updated on site and on the records. RAILWAY SAFETY 13
