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.

Famous quotes containing the words peak and/or hours:
“I think I’ve been good, but I want to be better. I think women reach their peak in their mid-thirties.”
—Mary Decker Slaney (b. 1958)
“In the middle of the night, as indeed each time that we lay on the shore of a lake, we heard the voice of the loon, loud and distinct, from far over the lake. It is a very wild sound, quite in keeping with the place and the circumstances of the traveler, and very unlike the voice of a bird. I could lie awake for hours listening to it, it is so thrilling.”
—Henry David Thoreau (1817–1862)
