At Peak Hours
At Bank, when a driver has stopped the train and disembarked the passengers, he has to let another driver from a previous train take over. This is known as stepping back, and happens because drivers do not have enough time to change ends. A Rear Cab Clear plunger has been installed on the track-side of the platform barrier so that the driver can confirm that he is clear of the cab and the "step-back" driver can depart when the signal clears.
