Study Notes
Deleted Items
- Abnormal working protocols removed for SR 9.12.01 to SR 9.12.08.
- SR 9.14.01 (a) regarding semi-automatic stop signals is set to manual when defective or ON, requiring T/369 (3b) authority.
- SR 9.14.01 (b) has similar manual requirements for departure signals.
- A&C No. 29 (T/375) instructions in the Incident Book (IB) have been revoked.
Revised Items
- SR 3.75.01(ii) specifies communication protocols for passing IB at ON via telephone with Private and ID numbers; normal speed details omitted.
- SR 3.74.04(a) allows passing IB at ON with authority T/369(3b) using Private number and ID number; hand signals are not required, applicable for both Single Line (S/L) and Double Line (D/L).
Means of Communication
- Fixed Telephone with CUG SIM to be included as a communication medium.
Authority Protocols
- T/C 912 is the authority for operating relief engines or trains on obstructed lines, applicable for both D/L and S/L.
- T/E 912 noted as the new authority during Track Log Signaling (TLS).
Added USR by Railway Board
- S.R. 9.12/1 outlines actions for signal failures between block stations, directing adherence to GR 9.02 or GR 9.07 without issuing T/A 912.
- S.R. 9.12/2 details protocols for prolonged signal failures, requiring senior personnel decisions and transitioning signals to manual mode initially.
- Loco pilots receive T/D 912 with authority to proceed with line clear and pass ON signals.
- Speed limits dictate the first train at 25/10 Kmph, with subsequent trains at sectional speeds.
- Procedures for passing stopping signals with hand signals and ensuring gates are secured.
- S.R. 9.12/3 establishes regulations for train operations under automatic block systems amidst line obstructions, requiring senior management decisions.
- First trains must confirm the previous train has arrived and abide by speed regulations and caution protocols.
- Signal authority includes specific instructions for right and wrong line operations and communication with station personnel.
Single Line Operations
- S.R. 9.12/4 governs single line operations amid communication failures, utilizing T/B 602 + T/A 912 without changing signals.
- S.R. 9.12/5 addresses single line guidance in double line scenarios during automatic signal failures; communication must be verified by engineering personnel.
Caution Orders and Speeds
- Speed regulations ensure 25/10 Kmph for first trains and maintenance of a 30-minute interval between subsequent trains.
- Protection measures enforce spacing requirements and specific operations outlined in directive protocols to maintain safety.
Summary of Authority
- Various authorities established for passing signals and train movements emphasize distinct protocols:
- T/A 912 permits passing signals and requires a caution order; speed limits established.
- T/B 912 allows movement without a line clear and mandates caution protocols.
- T/C 912 offers authority with caution processes for manual signal interactions.
- T/D 912 and T/E 912 define line clear requirements, linking them to respective signalling and speed protocols for different train scenarios.
