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:
“In the mountains the shortest route is from peak to peak, but for that you must have long legs. Aphorisms should be peaks: and those to whom they are spoken should be big and tall of stature.”
—Friedrich Nietzsche (1844–1900)
“Just getting in the pool for seven straight hours is unbearable to me.... It’s grueling. There’s nothing physically pleasurable about it. If you’re doing a hard workout, you’re throwing up in the gutter. At night you cling to your pillow and just hope that your body revives before you have to go back and do it again.”
—Diana Nyad (b. 1949)
