Study Notes

Communication Interruption Procedures

Total interruption of communications on double line sections requires specific protocols to ensure safety.
Preferred methods for obtaining Line Clear include block instruments, track circuits, and axle counters, in order of priority.
If communication fails, the Station Master must inform the Loco Pilot and Guard of the situation before the train proceeds.

Authorizations and Speed Restrictions

T/C 602 is issued to grant authority to proceed without Line Clear, including speed restrictions: 25 KMPH on straight sections and 10 KMPH in obstructed views.
Trains must stop at block sections, and safety measures, including hand signals, are crucial when the view ahead is not clear.

Safety Measures when Stopped

A clear interval of 30 minutes is required between trains entering a block section.
Fixed signals (except LSS) may be taken 'off' only after the train has stopped outside them.
Tunnels must be cleared before entry; if unsure, pilot the train with a railway employee using hand signals.

Emergency Procedure for Train Stoppage

If a train is stopped due to an accident or obstruction, the Guard must exhibit a stop signal and ensure proper warning devices (detonators) are placed at specified distances.
Backing a train is generally prohibited unless unavoidable; in such cases, protection measures must be in place.

Signaling Protocols

Before entering a tunnel, all train lights must be switched on to enhance visibility.
Approaching stations requires stopping outside the FSS and sounding a continuous whistle if no response is received within 10 minutes.

Communication Recovery Procedures

T/B 602 allows for opening communication after a failure; strict protocols are in place for emergency despatch of trains or locomotives.
A minimum interval of 30 minutes must be observed before dispatching additional trains in the same direction.

Procedure for Facing Obstructions

Trains must proceed with caution, utilizing appropriate speed limits when using T/B 602; visibility conditions dictate speeds (day, night, fog).
Personnel are required to accompany any self-propelled vehicles to ensure safety during operations.

Handling Split Trains

Specific procedures exist for splitting trains on single line token sections, demanding proper documentation from the Loco Pilot.
The Assistant Loco Pilot must exhibit signals to ensure clear communication and safety during the movement of coupled trains.

Station Coordination and Safety Checks

Upon arrival at a station, the Loco Pilot delivers a written memo and coordinates with the Station Master to check the completeness of the cargo.
The clearance of the second portion of the train must be safe, with speeds regulated by visibility.

Summary of Key Responsibilities

Station Masters are responsible for safe custody of T/C 602 and executing procedures for train operations during communication failures.
Loco Pilots and Guards must work collaboratively for the safe movement of trains, emphasizing precaution and clear communication at all times.

Train Communication Protocols

Station Masters must establish communication with the other end of an affected block section to manage train despatch.
Various vehicles can be sent to open communications, listed in order of preference: light engine, train engine, motor trolley/tower wagon, cycle trolley/moped trolley, diesel car/rail motor car/EMU rake.

Safety Procedures Before Dispatch

The Station Master on duty must brief the Loco Pilot, Motorman, Guard, or the accompanying Station Master about the circumstances and rules for train operations during communication disruptions.
A thorough understanding of protocol is essential for staff being sent for communications; if they lack knowledge, they must be instructed on the necessary rules.

Documentation and Authority

Upon entering the affected block section, the T/B 602 (Authority for opening communication) must be handed to the Station Master on duty for safekeeping.
The return journey authority is provided through a CLC message, leading to the issuance of a conditional line clear ticket (T/G 602 or T/H 602) for the return trip.

Return Journey Operations

If a vehicle returns without reaching the next station, the T/B 602 must be cancelled and recorded appropriately.
The Station Master must hand over a CLC message for line clear during the return, allowing clearance for any train waiting on the other side.

Operating Speeds and Signals

During return journeys, engines and self-propelled vehicles must adhere to predetermined speeds while respecting other operational rules.
Signals for train protection include Danger signals that must be shown until recalled, and specific actions are required when assistance is requested.

Protections for Stopped Trains

Loco Pilots must signal for protection if a train cannot proceed, using whistles and flags to communicate with the Guard.
Guards must visibly signal and ensure safety measures are in place for stopping any passing trains.

Coordination Between Crew

When protection is in place, the Guard and Loco Pilot must meet to consult and take necessary further action.
Upon readiness to proceed, a whistle signal is used to recall safety personnel for the train to advance.

Use of Detonators

Detonators should be placed as a warning signal at specified distances depending on the train type and section status whenever the train is disabled.
The Guard is responsible for ensuring proper deployment of detonators when protecting a train.

Emergency Signals Verification

Flasher light units on locomotives aid in visibility, and maintenance checks are mandatory.
Upon approaching a station with an obstructed block section, Loco Pilots must signal their status to the Station Master to prevent any obstruction clearing.

Arrival Procedures

Upon reaching the station, Loco Pilots must deliver written authority from the Guard to ensure the first part of the train's safe arrival.
Joint verification of the train load is conducted to confirm completion before proceeding further into the block section.

Guard's Authority

The Guard has the authority to prevent any train movement until written communication confirms it's safe to proceed, ensuring operational safety at all levels.
