Which end of a car is the master door controller located?

The master door controller is located at the No. 1 end of a train car to ensure efficient operation and management of the doors. This positioning allows the train operator or crew member in charge of the doors to have immediate control over access points when the train is stopped, aiding in passenger safety and the smooth boarding and disembarking process.

Locating the master door controller at the No. 1 end ensures that it is close to the primary cabin or operating area and aligns with standard practices in rail operations, where this end is typically designated for the train crew and entry/exit procedures. This configuration allows the train operator to efficiently monitor and manage the doors to respond quickly to any issues that might arise during operations.
