What’s the ‘tractive effort’ of a locomotive?

20-06-2019

The ‘tractive effort’ is a measure of how large a load the loco can pull and set in motion from a standstill — the maximum force it can exert at the drawbar or coupling. While the raw horsepower rating of the loco is important, it is not the whole story. The loco's weight also comes into play, as a heavier loco can pull a larger load without its wheels slipping. Once the wheels begin slipping, the force that can be exerted by the loco drops dramatically. (Slipping occurs more with the front wheels because the front of the loco tends to lift slightly due to the reaction torque exerted by the rails on the loco.) Modern locos tend to have electronic slip control to control the power

How is failure of signals guarded against?

June 21, 2019

Signal installations are designed as far as possible for fail-safe operation, which means that any failure should leave the system in a state where dangerous train movements are not allowed. For instance, in case of a failure detected at a panel interlocking installation, all signals controlled by it are designed to revert to On. Similarly, a

What is a ‘fixed signal’?

June 21, 2019

A fixed signal is any signal that is permanently erected at a location. The term is used to distinguish normal signals and indicators from hand or lamp and flag signals, detonators, flares, bells, and other special-purpose methods of signalling. ये भी पढ़े - योगासन का इतिहास तथा योग से

What does ‘ahead’ or ‘behind’, ‘advanced’ or ‘retarded’, or ‘front’ or ‘rear’ mean when referring to a track or signals?

June 21, 2019

All orientation terms used when talking about track, points, signals, stations, etc. are given from the point of view of the driver of a train looking in the direction that the train is moving. Thus, a signal may be ahead of him or behind him. A signal or station that he is approaching is referred to as being in front, and one that he has passed

Sometimes a signal pole is observed to carry one signal at normal height and another much higher up; what are those? Or, what are Co-acting Signals?

June 21, 2019

A co-acting signal is a duplicate signal provided on the same mast as a stop signal, which always shows the same indication as that stop signal. The purpose of such a co-acting signal is to allow a continuous unobstructed view of the signal indication from all positions where a driver might need to observe it, in cases where an overbridge or other

What does it mean when a colour-light signal does not face along the tracks but points away?

June 21, 2019

Colour-light signals that are not in use (just set up but not yet commissioned, or in the process of being decommissioned) are often turned to point away from the tracks, so that it is clear to all locomotive drivers that the signal is not in service. Otherwise, it would be treated as an active signal that is malfunctioning (lamps burnt out),

What do the rings, bars, etc. found on some signals mean?

June 21, 2019

Stop signals controlling the approach to goods yards or goods-only lines have a black ring fixed to the end of the semaphore arm. No corresponding indication is provided in colour-light territory. Similarly, semaphore signals controlling lines for dock platforms have a black semicircle (in the shape of a 'D') fixed to the end of the semaphore arm.
