Yo! Indians must be aware of this i guess. The Indian railways is one which is started by The Great Britan when they conquered India. And after independence in the year 1947 the railways has shown a considerable improvement. One of this is GPS has been installed in all the Trains, and the passengers can see in a electronic display where they are and how many more KM are there for the next stop. and what is the next stop. and other related information. And because of this all the Railway stations can have a good grip on the running trains. Before this system there was an old system which was intorduced by the British " Token Passing " in the Trains . That is when one train crosses a station they will pass a Key to the station and inturn get another key from the railway station.

I remember watching this scene when i was a small kid. As the train approached the station, if the train has a halt there then it is well and good. The key is passed in a simpler manner. Just imagine if the train dosent have a stop in the railway station, they will throw the Key to the ground ( The key is a small ball here which is tied up in a bamboo frame which looks like a shuttle racket ) . Now in the moving train too the driver has to get a key for this a guy stands near the moving train and raises the key and gives it to the engine driver of the moving train. The engine Driver grabs the bamboo striucture with much force. This was the previous system. In this system just imagine the key passing thing which is done at night. At night the guy standing in the railway station will hold a torch lit by flame in one hand and the key in the other hand and the key pass is done.This is how they used to track the running trains before in India.

But now with GPS being installed in the running trains all this old system is no longer into existence. Yeah India is Developing.
