Procedure for train movement when communication between block stations is completely lost.

Order of preference for obtaining 'Line Clear' during communication interruption.

Obtaining permission to move a train when communications are down, each train needs separate identification number.

When block instruments stop working, creating total communications outage.

Alternative communication for "Line Clear" in emergencies.

The special instructions for the duration and manner of VHF usage during communication issue.

Violation of the preferential order in communication method usage will be faced with strict action.

When communication is down, confirming the safety of a track section for train movement.

A complete failure of communication between block stations, making regular train signaling impossible.

Methods for obtaining "Line Clear" when regular communication with block stations is unavailable.

The station master is responsible for obtaining "Line Clear" and dispatching trains when regular communication is down.

Specific order of preference for methods used to obtain "Line Clear" during communication outages.

A locomotive without any train cars attached, used as a primary communication method.

A train's engine can be detached and used for communication if a light engine is unavailable.

A motorized trolley or tower wagon, used for communication if no engines are available.

VHF radio sets are not allowed for obtaining "Line Clear" when Global System of Mobile Radio is available.

The Station Master must inform the Loco Pilot/Motorman/Guard/Station Master of the situation and the purpose of the mission. They must also ensure the staff understands the rules for working trains during total communication failure.

The Station Master must obtain the signature of the Loco Pilot/Motorman/Guard/Station Master on the "Authority for Opening of Communication during Total Interruption of Communication on Single Line Section (Form T/B 602)".

The document includes an "Authority to Proceed without Line Clear", a Caution Order specifying the speed limit for the vehicle, and permission to pass the last stop signal if applicable.

The Caution Order specifies the maximum speed at which the vehicle can travel towards the affected block section.

This document authorizes the vehicle to proceed towards the affected block section even without a traditional "Line Clear" signal from the Station Master.

The document must include an "Authority to pass the last stop signal in the "On" position", allowing the vehicle to pass the signal even when it is in the 'On' (stop) position.

Examples include: Light engine, Train engine, Motor trolly, Tower wagon, Trolly, Cycle Trolly, Moped Trolly, Diesel Car, Rail Motor car, EMU, MEMU, DMU rake

These rules ensure safe train operation when traditional communication methods are unavailable, preventing collisions and accidents.

The Station Master on duty makes these decisions, informing the Loco Pilot/Motorman/Guard/Station Master accordingly.

The Station Master has the responsibility to ensure that the Loco Pilot/Motorman/Guard/Station Master fully understands the rules for safe working of trains during total communication failure.

The Station Master is responsible for obtaining "Line Clear" authorization for train movement during total communication interruptions. They also handle documents, maintain records of the Line Clear process, and communicate with other stations.

A "Conditional Line Clear" is an authorization issued during a communication outage that permits a train to travel towards a certain station, but it's contingent on the arrival of a communication enabling signal to the other station.

The "Authority for opening communication during total interruption of communication on single line section" document (T/B 602) is used to authorize train movement during a full communication outage.

The Conditional Line Clear Ticket (T/G 602 or T/H 602) is issued by the Station Master during a full communication outage and is given to the Loco Pilot/Motorman/Guard/Station Master to return to the block station they came from.

The "Conditional Line Clear Reply Message" is used to inform the other Station Master that the train has arrived at their end, allowing them to start any trains waiting at their location during a communication outage.

No obstruction is allowed on the line beyond the outermost facing points until the return of any engine, rail vehicle, or trolley. This prevents accidents during communication outages.

When two engines or vehicles meet in the middle of a single-line section with communication outages, the Loco Pilots, Motormen, or Station Masters must decide which station each vehicle will proceed to based on various factors such as train importance, distance to the nearest station, and track gradients.

If possible, two engines or vehicles meeting in the mid-section should be coupled up before proceeding. This enhances safety and allows for controlled movement.

When a motor trolley or similar vehicle encounters an engine, it should, if possible, be loaded in the engine's Brake Van. This ensures passenger safety and allows the engine to proceed.

When approaching the station, the leading engine or vehicle should stop outside the first Stop signal. This allows for communication and confirmation of the 'Line Clear' before proceeding.

'Line Clear' is crucial for the safe movement of trains, especially during communication outages. It ensures that the track section ahead is clear and safe for the train to proceed.

In the absence of regular communication, engines or self-propelled vehicles can be used to establish contact with other stations or engine crews. This allows for coordinating train movement safely.

When using alternative communication methods, a clear order of preference needs to be followed. This ensures that the most reliable and efficient method is used first.

When engines or vehicles are unable to couple, they should maintain a safe distance while running. This provides buffer space and prevents collisions in case of emergencies.

This refers to a situation where communication between block stations on a single-line section is completely lost, making it impossible to use standard signaling procedures for train movement.

When communication fails on a single line for more than three hours, the Sectional TI or supervisory Station Master must go to the affected station to assist staff and ensure strict adherence to procedures for issuing train authorizations.

During a communication outage, the Section Controller must ensure that no crossing or precedence (priority) is allowed at the station where the failure persists.

A speed restriction of 30 kmph is imposed during communication outages on single-line tracks. Additionally, if the working train on a PLC (Programmable Logic Controller) exceeds 24 hours, another 30 kmph speed restriction is added on top of the existing communication outage speed restriction.

If the senior supervisors fail to reach the station where the communication outage occurred within the stipulated time and a mishap occurs, they are held equally responsible. Even superiors who prevented the supervisor from reaching the station are held accountable.

The procedures outlined for handling communication outages must be implemented immediately, and the 30 kmph speed restriction due to communication outages should be discontinued.

If communication is fully interrupted between block stations, special procedures are followed to ensure safe train movement.

The 'Authority for opening communication during total interruption of communication' form is used to authorize train movement.

A 'light engine' (locomotive without cars) is sent ahead to open communications with the next station.

A 'Caution Order' specifies the maximum allowable speed for these vehicles.

If two vehicles meet in the middle of a single-line section with communication outages, they must coordinate their movements.

An engineer on a push trolley can enter the section, but only if the 'Line Clear' process is followed for other trains.

Engines, self-propelled vehicles, trolleys, cycles, moped trolleys, diesel cars, rail motor cars, EMUs, MEMUs, and DMU rakes can all be used for communication.

The Station Master is responsible for ensuring that the Loco Pilot understands the communication failure rules and procedures.

This message is used to inform the other Station Master that a train has arrived at their end, allowing them to start any waiting trains during a communication outage.

This ticket is issued by the Station Master during a full communication outage and given to the Loco Pilot/Motorman/Guard/Station Master to return to the block station they came from. It confirms that the train has arrived safely.

This book is used to record the 'Conditional Line Clear Reply Message', providing a formal documentation of the communication during a full communication outage.

A 'light engine' (locomotive without cars) is sent ahead to open communications with the next station during a communication outage, establishing contact and enabling safe train movement.

When communication between block stations is completely lost, trains can't be signaled as usual. Special procedures kick in to keep things safe.

The Station Master is in charge. He makes sure it's safe for trains to go based on the 'Line Clear' status.

This document is like a special permit for a train to move when communication is down. It contains important rules for how to proceed.

The Station Master gives this to the engine driver when communication is down. It authorizes them to proceed to the next station.

This message is sent back to the Station Master when an engine arrives at the other end, letting them know it's safe to start any other trains waiting.

Special vehicles like light engines, motor trolleys are used to restore communication. This allows the Station Master to grant line clear to trains.

They need to decide which station each one will proceed to. Factors like train importance, distance, and track gradients are considered.

If the train cannot stop at a station, the 'Authority for opening communication' document will allow the train to pass the stop signal.

A 'Line Clear' is the authorization that confirms the track ahead is clear and safe for a train to proceed, especially important when communication is down.

To get a 'Line Clear,' the 'Authority for opening communication during total interruption of communication' document is used to authorize train movement, usually by a light engine which makes contact with the next station.

A 'Caution Order' dictates the maximum allowed speed for a vehicle proceeding on 'Line Clear' authorization. It's a safety measure.

When two engines meet in the middle of a single-line section with communication outages, they must coordinate their movements to decide which station each vehicle will proceed to.

Vehicles like engines, trolleys, cycles, moped trolleys, diesel cars, etc. can be used to establish communication. Their role is to get in contact with the next station to resume safe train operations.

The Station Master is responsible for ensuring the Loco Pilot understands communication failure procedures and has the necessary authorization to move the train safely.

Examples of vehicles used to open communications include: Light engines, Train engines, Motor trolly, Tower wagon, Trolly, Cycle Trolly, Moped Trolly, Diesel Car, Rail Motor car, EMU, MEMU, DMU rake.
