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

What gauges are used in India?
July 17, 2019

This is now found all over the country, and all major passenger and freight routes are now broad gauge. This is the widest gauge in regular use anywhere in the world. (In the past, though, an 8' gauge was used in Oregon, USA, and a 7'¼" gauge was used for the Great Western Railway in the UK.) Outside India, the 5'6" gauge is found in Pakistan, a

Have any marshalling yards been closed down?
July 17, 2019

Yes, many marshalling yards have been closed over the years, especially since the 1980s, with the move towards using block rakes that do not need to be broken up and re-classified all the time. A list of closed yards is given below. Central Railway Amla (BG) Agra Cantt (BG) Wardha (BG) Nishatpura (BG) Balharshah (BG) Bina (BG) Jabalpur

Where are the important marshalling and stabling yards?
July 17, 2019

Most of the bigger stations that are junctions or termini for various routes have large yards for stabling and marshalling rakes. E.g., Chennai Central homes rakes for many trains originating from there. Pune has a fairly large yard, as does Ernakulam. The Juhi marshalling yard is pretty big as well. Mughalsarai is the biggest marshalling yard in
