With reference to above, a four-member SAG committee, formed by Railway Board
has formulated Unified Subsidiary Rules to General Rules 9.12 to be followed in Automatic
Block System. The main objective has been to provide clear instructions to Station Master,
Loco Pilot and Train Manager for working of trains during failure of Automatic Signalling
and to minimize the number of paper authoritiesto be issued to Loco Pilot and Train
Manager during such failures. The salient aspects are as follows:

1. New para 9.12/1 has been added that states that during failure of signal/s in
Automatic Block System train operation will be done in accordance with rule-9.02
(DL) and rule-9.07 (SL).

2. The forms — T/A 912, T/D 912, T/B 912, T/C 912, T/B 602 & T/510 have been
reframed as per the conditions in which they are to be issued (including one or more
of the following authorities):

a) Condition of passing signal at ON

b) Authority to Proceed without Line clear

c) Circumstance under which authority is given

d) Caution order specifying the Speed to be followed

e) Line clear ticket

T/C 912 — shall be used for sending Relief Engine/Train on the obstructed line in
case ofobstruction or accident in an Automatic Block Signalling section.

3. Different procedures are being followed in various Zonal Railways for temporary
single line working in Automatic Block Signalling territories. To standardize the
various procedures being followed, a new form T/E-912 has been introduced
“AUTHORITY FOR TEMPORARY SINGLE LINE WORKING ON DOUBLE
LINE AUTOMATIC BLOCK SIGNALLING TERRITORIES”.

4. Unified SR 9.12 has been framed to cater to train working rules in cases of failures
which are common in nature to all zonal railways. Special cases would vary from
railway to railway. In the proposed USR the basic principle of train operation during
failure of Automatic Signalling in double line and single line section has been dealt
with. The same principles should be used/applied for train operation in special cases
(like Quadruple lines, Hexaple lines etc.) by the railways.

5. Presently, no guideline is prescribed for passing a Semi-Automatic signal in ‘ON’
or defective condition. Provision of issuing form T/369(3) has been made for the

IPN V4

same. Standard format of T/369(3b) with relevant modification is also being issued
along with the unified Subsidiary rule. T/A 912 shall not be used for such cases.

6. Use case of T/A 912 has been defined clearly and has not been used as a standalone
authority.

7. Fixed Telephone with CUG sim is being permitted as a means of communication.
Following procedure is suggested:

a) The CUG phone may be used as FCT (Fixed Cellular Telephone).

b) Every Station should have a unique CUG number and the same should be
mentioned in the Working Time Table.

c) The CUG phone should be always with the ‘On Duty’ Station Master and handed
over to the reliever in writing as per essential equipment.

d) CUG based FCT phone may be provided at the time of commissioning of
Automatic Signalling Territory.

8. The summary of The Unified Subsidiary Rule of General Rule 9.12 is as below:
S.R. 9.12/1: - In case of failure of signal or signals between two or more block
stations in Automatic block system.

S.R. 9.12/2 (A):- Failure of signal/s between two or more block stations in
Automatic block system likely to last for some time or cause serious delay when
means of communications are available.

S.R. 9.12/2 (B):- Failure of all signal
