Instructions pertaining to Unified Subsidiary Rules under GR 9.12, By Railway Board on 16.08.2024 Railway Board Ltr on 16.08.2024 on formulation Unified Subsidiary Rules under GR 9.12, it will be implemented in Zonal Railways after issuing Addendum and Corrigendum slip of G& SR from concern Railway.  As Per GR 9.12 9.12. Procedure during failure of Automatic signalin When a failure of Automatic signaling is likely to last f some time or cause serious delay, trains shall be worke from station-to-station over the section or section concerned under special instructions. instructions nified Subsidiary Rules to General Rules 9.12 to be followed Automatic Block System”. he main objective of the committee was to provide cle structions to Station master, Loco Pilot and Train Manager orking of trains during failure of Automatic signaling and inimize the number of paper authorities. authorities he committee was recommended the following provision in t nified Subsidiary Rules to GR 9.12 12. New para 9.12/1 has been added that states that during failure gnal/s in Automatic Block System train operation will be done ccordance with rule-9.02 (DL) and rule-9.07 (SL).  he forms – T/A 912, T/D 912, T/B 912, T/C 912, T/B 602 & T/510 e been reframed as per the conditions in which they are to be iss luding one or more of the following authorities) :- : Condition of passing signal at ‘ON’ Authority to Proceed without Line clear. Circumstance under which authority is given Caution order specifying the Speed to be followed ine clear ticket T/C-912 – shall be used for sending Relief Engine ain on the obstructed line in case of obstruction or accident in an omatic Block Signaling section. Different procedures are being followed in various Zonal Railways porary single line working in Automatic Block Signaling territories standardize the various procedures being followed, a new fo -912 has been introduced “Authority Authority For Temporary Single L rking On Double Line Automatic Block Signaling Territories”. Unified SR 9.12 has been framed to cater failures which mmon in nature to all zonal railways. railways Special cases would vary f way to railway. In the proposed USR (Unified Subsidiary Rule) ic principle of train operation during failure of Automatic Signalin ble line and single line section has been dealt with. The sa nciples should be used/applied /applied for train operation in special ca e Quadruple lines, Hexaple lines etc.) by the railways.  Presently, No Guideline is prescribed for Passing a Sem omatic Signal at ‘ON’ (or) Defective Condition. Provision uing form T/369(3b) has been made for the same. Standard form T/369(3b) with relevant modification is also being issued along w Unified Subsidiary Rule. T/A 912 shall not be used for su es. Use case of T/A 912 has been defined clearly and has not be d as a standalone authority. Fixed Telephone with CUG SIM is being permitted as a means mmunication. Following procedure is suggested: he CUG Phone may be used as FCT (Fixed Cellular Telephone).  very Station should have a unique CUG number and the sa uld be mentioned in the Working Time Table. he CUG phone should be always with the ‘On Duty’ Station Mas handed over to the reliever in writing as per essential equipment.
