How is waiting time so less for metro trains in India given the fact that the tracks are straight and not in a loop. I want to ask how many trains/how do these trains work on a single one way track? Like does a train go from end to end ? If yes, then how is waiting time so less ?

Often metro systems work on a ‘stepping back’ system. So when a train arrives at the terminus, the driver 1 gets out and starts walking towards the front of the train. Meanwhile a driver 2 that was waiting at the end of the platform steps in and starts away.
Driver 1 is then waiting at the end of the platform when the next train comes in.
