Hi there... Just watched a video in which the driver of the express train puts on the brake to make the train still in a very short span of time. Before putting on the brake, the train was moving close to 100 km/hr. Just googled the braking system being used in Indian Railways and found that two braking systems are being used viz. Air Brakes and vacuum brakes. just not able to distinguished one another. So if any member of IRI have any knowledge of Braking system, kindly let the other RailFans who do not know, come to know the magic of stopping a fast moving train in a few seconds.. Thanks..
