Responsibilities s are mandatory on all members of the Railway Group* and apply to all activities which fall within the scope of each individual s Railway Safety Case. If any of those activities are performed by a Contractor, the contractor s obligations in respect of s is determined by the terms of the contract between the respective parties. Where a contractor is a duty holder of a Railway Safety Case then s apply directly to the activities described in the Railway Safety Case. *The Railway Group comprises Railtrack, the duty holders of Railway Safety Cases accepted by Railtrack and the British Railways Board as long as it owns train operators. Implementation The requirements of this are mandatory and replace those in Issue 1 from 1 February Health and Safety Responsibilities In authorising this Standard, Railtrack PLC makes no warranties, express or implied, that compliance with all or any s is sufficient on its own to ensure safe systems of work or operation. Each user is reminded of its own responsibilities to ensure health and safety at work and its individual duties under health and safety legislation. 2 R A I L T R A C K

6 Page 4 of 16 Withdrawn Document Part B 1 Purpose To support traceability and maintenance of records, this standard mandates the branding of all wheels, tyres and axles of rail vehicles operating on Railtrack infrastructure. 2 Scope The requirements of this standard apply to all wheelsets for use on rail vehicles to be operated over Railtrack controlled infrastructure, except Foreign registered vehicles accepted for international running under RIV or RIC Regulations. 3 Definitions Cold Stamping Stamping performed on the component while it is at ambient temperature and in the finished condition. Competent Organisation An organisation which employs staff with the necessary skills, experience and knowledge to undertake specific tasks. Engineering Director Engineer responsible to a railway business, independent train operator or vehicle owner for the engineering management of traction and rolling stock. Hot Stamping Stamping performed on the component in the heated state during manufacture. Rail Vehicle Any vehicle described as traction and rolling stock (ie locomotive, coaching stock or wagon) or on-track machine. Re-Wheeling/Re-Tyring The terms re-wheeling/re-tyring apply to the replacement of any wheel, wheel centre or tyre, whether new or used, fitted to existing wheelsets. 4 Safety management All applicable statutory safety regulations shall be observed in applying this standard. The operations shall be performed in such a way that they do not constitute unacceptable hazards to any person at any time between wheelset manufacture and withdrawal from service. 5 Branding 5.1 All monobloc wheels, wheel centres, tyres and axles shall be requirements legibly branded in accordance with the requirements of this Railway Group Standard, (). 4 R A I L T R A C K

7 Page 5 of The stamps used for branding shall be scroll or block stamps of 6mm minimum height with rounded edges and corners approved by a Competent Organisation, see Section Each new axle shall be provided with a unique serial number, allocated from the assembling contractor s own series of numbers. Particular attention must be paid to the provision of the appropriate assembling contractor s code, see Table 1 of GM/RM2525 INF for list of recognised contractors and their codes. 5.4 Manufacturers/assemblers who have been prequalified by the BR Board or who have been accredited by a Competent Organisation in accordance with GM/RT2450 as suppliers of wheelsets, shall obtain from Railtrack, Safety and Standards Directorate, Head of Train & Train Systems Unit specific wheelset manufacturer/assembler codes. 5.5 Any original branding that is either removed or obscured by any subsequent machining or other remedial processes carried out shall be reinstated to the requirements of this (). For wheels, wheel centres or tyres, this shall be by COLD stamping in the locations specified. 5.6 All branding specified in this shall remain clearly legible after the application of any surface finish coating. This applies to both initial assembly and any subsequent overhaul. 5.7 When any details are changed or new components fitted (e.g. tyre profile etc.) the previous branding on the wheel hub shall be peened out and erased by filing. The new data shall be stamped in the relevant location as required by this standard. The erasing process shall be agreed by a Competent Organisation, see Section At overhaul and reassembly of wheelsets it shall be checked that the axle serial number is not duplicated and that the branding conforms with the requirements of this standard (). Note: There is a national scheme for registering axle numbers on RAVERS. 6 Records This document shall be used in conjunction with the standard GM/TT0083, which covers the mandatory requirements for wheelset records.

To ensure that the serial number is unique the Assembling Contractor s Code must always be quoted as part of the axle serial number. (See also the requirements of sub-section 7.3.) 7.2 Under no circumstances shall a replacement axle be given the serial number of an original axle. 7.3 Where the axle serial number stamped on an existing axle (as formed by the assembling contractor s code and following number) is not unique or that an Assembling Contractor s Code is not present, the latest assembling Contractor shall allocate an axle serial number from its own number series. The previous axle serial number shall be recorded for reference purposes. Note: Axle serial number prefixes and suffixes different from those shown in this standard may be found. Such serial numbers relate to earlier Manufacturing and Assembling Contractors; however, the important requirement is that the stamping is alpha-numeric and unique to that axle. Known obsolete axle number prefixes and suffixes are shown in GM/RM2525 INF for reference purposes only. 8 Manufacture The branding of wheel centres shall be in accordance with Fig 1. branding of wheel centres 9 Manufacture The branding of tyres shall be in accordance with Fig 2. branding of tyres 10 Manufacture The branding of monobloc wheels shall be in accordance with Fig 3. branding of monobloc wheels 11 Manufacture 11.1 Roller bearing axles shall be branded in accordance with items 2, 3, branding of axles 4 and 5 of Fig 4. (as forged condition) 11.2 The branding of plain bearing axles shall be in accordance with items 2,3,4 and 5 of Fig Manufacture In order to maintain clarity of identity the branding for the finished branding of axles machined axle shall be carried out as soon as the areas to be (finished machined condition) stamped have been machined Roller bearing axles shall be branded in accordance with items 6, 7 and 8 of Fig 4. 6 R A I L T R A C K

9 Page 7 of Plain bearing axles shall be branded in accordance with items 7 and 8 of Fig Axles over Axles over forty years old from the date of manufacture shall be forty years old identified by stamping an X in front of the Manufacturing/Assembling Contractor s code when the next wheelset repair or overhaul in accordance with GM/RT2027 takes place. 14 Assembly branding 14.1 Both wheels shall be branded on the inside face of the wheel in of monobloc wheels accordance with Fig Where stamping is not practicable on the inside of a wheel due to the close proximity of the gearwheel to wheel, or for other reasons agreed by the responsible Engineering Director, then it is acceptable to stamp at the outside location only. 15 Assembly branding 15.1 Both tyres shall be branded on the inside face of the wheel in of tyred wheels accordance with Fig Where stamping is not practicable on the inside of a wheel due to the close proximity of the gearwheel to wheel, or for other reasons agreed by the responsible Engineering Director, then it is acceptable to stamp at the outside location only Branding on the tyre outside face shall be located adjacent to the manufacture branding. 16 Assembly branding Assembled wheelsets shall have the axle end branded as follows:- of axles i) Roller bearing axles shall be branded in accordance with Fig 8. ii) Plain bearing axles shall be branded in accordance with Fig Axle geometry The axle geometry codes specified in Table 3 of GM/RM2525 INF codes shall only be added after the serial number for the following axles:- i) Axles reclaimed by modifying their geometry. ii) Replacement axles where the geometry of the new axle differs from the original due to the inclusion of transition radii, stress relief grooves, etc. R A I L T R A C K 7
