Why is the neutral section provided with a dummy (neutral or electrically dead) cable? Why can’t it be a real gap?

22-06-2019

Pantographs of electric locomotives have a spring mechanism or compressed-air assembly that keeps the pantograph pushing up against the contact wire with a certain specific pressure. If the neutral section were not wired and the contact wire simply ceased to exist, then then possibility exists that if the driver has not dropped the pantographs at the time the loco reaches the neutral section, then the pantograph will suddenly rise upwards unchecked; when the loco reaches the other end of the neutral zone, it is then likely to smash into the catenary where the next contact wire section begins. It should be noted that in practice, at neutral sections where it is or was a requirement to drop

What are catch and slip sidings? How are runaway trains managed?
July 17, 2019

Catch sidings are sidings provided to divert runaway trains off the main line on approach to a station, or on steep downward slopes. Points are normally set to route all trains to the siding, which may end in a sand trap to slow down and halt any train that is moving too fast and out of control. This prevents runaways from entering station or yard

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

How are runaway vehicles and out-of-control trains dealt with?
July 17, 2019

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. But here we focus only on train working guidelines which come into play for accidents.) The general principle is to protect the

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
