1 Control Command & Signalling Standards Brief Sept 2014 Professional Head [S&C] 11/11/2014 1

2 General This presentation gives headline details of the September 2014 Signalling Standards Brief It contains only those standards issued by the Professional Head [Signalling], or for which he is responsible Further details on the changes to the standards can be obtained from the contact name/details on the briefing note (this is part of the electronic document on Connect/IHS) 11/11/2014 3

3 General This presentation relates to updated standards first published in: September 2014 issue of the Railway Group Standards Catalogue from the RSSB. Company standards issued since the June 2014 meeting. 11/11/2014 4

4 Catalogue of RGS The September 2014 issue of the RGS Catalogue will be the last catalogue produced by RSSB. Currently all definitive versions of Railway Group Standards and associated documents are published on (the website is RSSBs Catalogue of Standards). Specifying your criteria via the Advanced Search (the last tab on the top blue navigation bar) the user is able to export their results from their search into an Excel spreadsheet. This excel spreadsheet could be created by yourselves as and when necessary. It contains all the information relevant to the document and can be used to filter on criteria that is appropriate to you e.g: Lead Standards Committee, Issue Date, Withdrawal Date, Document Status (Live/Withdrawn/Superseded) etc. RSSB will still publish a list of what is issued and withdrawn per publication period which will be available on the Latest Updates Page of 11/11/2014 7

5 Railway Group Standards GK/RT0075 (3) (inc GK/GN0675 (3)) Lineside Signal Spacing and Speed Signage It is considered that these changes do not adversely affect risk and will provide benefits to the design and use of lineside signal spacing and speed signage. Compliance for the superseded sections of GK/RT0075 is from 06/12/2014 and this is when issue 2 ceases to be in force. Repeater warning board The current layout of the TSR repeater warning board with the speed at the top of the board and R beneath has been reversed, with the R uppermost and the speed beneath. This change is intended to eliminate the problem that arises when the sign is erected off the end of a platform and the R is not visible to approaching trains and only the speed can be seen. 11/11/2014 8

6 Railway Group Standards Changes to braking distances Corrections have been made to the braking distances in Table B.1 Composite table for passenger trains (metres). The braking distances in Table B.1 for speeds of 95 mph and above on a rising gradient of 2.5 mm/m have been reduced by 5 m. For speeds of 100 mph or more on falling gradients of 2.5 mm/m the braking distances have been reduced by 2 m. These reductions in distances correct inconsistencies in the RGS but are not considered to have any wider operational implications because of the conservative derivation of the braking distances. The distance shown in Table X-3 of GK/RT0075 issue two, for decelerations to a speed of 30 mph from initial speeds of 75 mph and 80 mph on a gradient of 200 falling have been corrected from 1247m to 1358m. 11/11/2014 9

7 Railway Group Standards Removal of risk assessment before an ESR is applied Removal of an unintentional requirement for a risk assessment to be undertaken before placing an ESR. An ESR is used to control an immediate hazard in the short term and is normally implemented by permanent way staff with support from signalling technicians when required. As these groups of staff are unlikely to have the necessary information available to them, it is not practical in these timeconstrained circumstances for them to prepare a competent risk assessment, especially out of hours. The SPAD risk assessment is undertaken when the ESR is converted to a TSR. 11/11/

8 Railway Group Standards Withdrawal or increase of speed of TSR A change has been made to clause D of GK/RT0075 (2), to include a reference to repeater warning boards at a TSR, in addition to speed indicators and warning boards. The amended text reads: If the implementation of a temporary speed restriction is published or notified, and then its speed is raised earlier than planned, the speed indicators, warning boards and repeater warning boards shall: a) Remain in the same position until the published time and date for their removal, and b) Be altered to show the higher speed. This change to include reference to repeater warning boards has been made to align GK/RT0075 issue three with the Rule Book. The repeater warning board needs to be consistent with the TSR speed. 11/11/

9 Railway Group Standards Removal of TSR termination board Clause D in GK/RT0075 (2) which permits the removal of the TSR termination indicator, if the temporary speed restriction is not imposed or withdrawn, after having been published in the Weekly Operating Notice, has been deleted. This change has been made to align with the Rule Book. The requirement has been withdrawn because train drivers expect to see a set of three boards associated with a TSR and if a termination board is not present they would report it as a missing sign. 11/11/

10 Railway Group Standards Variation in actual signalling braking distance The requirement in GK/RT0075 (2), for a risk assessment to be undertaken when there are large variations in the signalling braking distances between sequences of signals on the same line, has been made to improve clarity and remove potential ambiguity with its application. The revised wording of the requirement achieves the intent of the original requirement and does not relax the criteria for when an assessment to determine that the signalling braking distance is compatible with the SPAD risk mitigation measures is to be undertaken. Clause b) currently reads: b) A variation in excess signalling braking distance means that the distance between the signals displaying the first cautionary aspect and the stop aspect is reduced by 34% or more, compared with the excess signalling braking distance for the preceding sequence of signals on the same line. Clause b) now reads: b) A signal has an actual signalling braking distance less than 67% of the actual signalling braking distance for the preceding signal(s) on the same line. 11/11/
