Thanks Sir, did not think at first glance that so much smoke might come out from the brakes.

Not exactly a brake-binding scenario, I would say. The driver just started to apply the brakes during the descent to keep a control over the speed and the first result is the appearance of "smoke" at the loco wheels. Nevertheless, a fantastic picture of such a "smoking" phenomenon.

Certainly an informative picture. The "smoke" is because of production of microscopic particulate matter due to the effect of friction between wheel and the cast iron brake pad. When the brakes are applied, the brake pad which is softer, disintegrates faster. During disintegration, the frictional heat oxidizes the softer cast iron brake pad and what you see as "smoke" is nothing but this iron oxide particulate suspension in air. Not surprisingly, the oxidation of iron occurs at the wheel-brake pad interface and therefore one sees the "smoke" coming from the wheels. Needless to add that inhaling this "smoke" is injurious to health :-)

The collector pan of the panto of WCAM1 is also unique

Nice shot, really. But how did the smoke originate? Is it the diesel fume turned white?

Wonderful shot!

This same thing happened to the MEMU at Saphale in which me, Arzan and Apoorva travelled yesterday.
