How are phase breaks (AC) or power gaps (DC) handled by the locomotives?

22-06-2019

The catenary has breaks or gaps in its electrical continuity every once in a while at points where successive sections are connected to different substations. A neutral section of catenary is usually provided between the two live sections of different phases or connected to different substations. At such points, single locomotives do not drop their pantographs, although on-board equipment such as the traction motors, compressors, blowers, etc. are switched off manually by the driver before the neutral section is entered. The main circuit breaker (DJ) is also opened. (Warning boards at 500m and 250m before the neutral section are provided for this purpose). (Earlier, locos used to routinely

What happens when the Alarm Chain (Emergency Chain) is pulled in a coach? (ACP, Alarm Chain Pulling)
July 17, 2019

The alarm chain in a passenger coach is designed to create a break in the continuity of the brake pipes (whether vacuum or air brakes), immediately resulting in a loss of brake pressure (or vacuum) and thereby cause the train brakes to be applied. With vacuum brakes, a clappet valve is provided that is released by the pulling of the alarm chain,

How is train parting dealt with?
July 17, 2019

If a train parts en route with a coupler failure, the guard uses his brakes to attempt to slow down his portion of the train to a safe halt. (If the train is being banked, the banker brings the train to a halt on seeing the guard's signal, and also sounds a danger signal to attract the attention of the driver in front.) If the front portion of the

In case of trains passing signals at danger or running through a station out of control, or moving on block sections without authority to proceed, the station master must inform the next station ahead of this occurrence (and on controlled sections must inform traffic control). The station master of that station then sets its departure and

What are the train working procedures in case of accidents, derailments, etc.?
July 17, 2019

(Naturally, there are well-defined rules on obtaining medical help and emergency services, etc. in the case of accidents, and assisting injured people and preventing further injury or death takes the highest priority.

When can trains be run without brake vans or without guards?
July 17, 2019

Normally, all trains are required to have a brake van or guard's van and a guard on board. However, in a few cases the brake van and the services of the guard can be dispensed with, especially in sections where block sections are completely track-circuited, which reduces the possibility of undetected train parting. Brake vans can also be dispensed

How are trains run in the fog?
July 17, 2019

Due to restricted visibility in thick fog which pervades northern India in particular during the winter months, trains are known to get delayed and schedules get thrown haywire. Obviously, these delays have their genesis in the fact that the drivers can't see the signals at sufficient distance and have to reduce speeds when approaching signals, so
