One set of door controls is provided in the cab to close all the doors at once. A door opening chime is played when the doors open. The conductor sticks their head out the cab window to observe the platform and doors, and when the doors are clear, they will press a button that closes the doors. At exactly the same time, door closing chimes are played, followed by an automated announcement of "please stand clear of the doors". The conductor will use the buzzer to notify the motorman that the train can proceed.
