When was air-conditioning introduced in IR?

22-06-2019

The North-Western Railway introduced air-conditioned stock in the late 1930's (the earliest was probably the Frontier Mail in 1936 or 1937). BBCI Railways also experimented with air-conditioning at about the same time. By the early 1950's, air-conditioning was available on several long-distance trains. For example, in 1952-53 there were air-conditioned services between Bombay and Howrah, Delhi and Madras (Grand Trunk Exp.), Bombay and Delhi, Bombay-Amritsar (Frontier Mail), Bombay-Viramgam (Saurashtra Mail), and Bombay-Ahmedabad (Gujarat Mail). These all used AC units that were mounted beneath the coach body (underslung), interconnected by pipes. Self-contained roof-mounted units appeared

How are trains run when tracks are flooded?
July 17, 2019

Flooding is very dangerous to the permanent way. The earthworks become unstable, ballast can be washed away, and the forces of the water by its movement, buoyancy, and scouring action can seriously weaken and move the track so that it is no longer stable and secure enough to support the weight of a train reliably. Hence, great care is taken when

Why do trains sometimes slow down on some sections instead of continuing at the same speed throughout?
July 17, 2019

There are many reasons for a reduction in speed. There may be permanent speed restrictions on the section of track: because of sharp curves or curves with inadequate cant; approaches to crossovers, diamonds, etc.; structures too close to the track; ghat sections; lineside tenements or pedestrian traffic; level crossings; old bridges or culverts;
