Where are master door controllers located on R44 and R46 cars?

The master door controllers for R44 and R46 subway cars are indeed located at the No. 1 end of the car. This positioning is essential for operations, as it allows the train operator or crew member at the front of the train to manage the doors effectively during boarding and disembarking processes.

Having the master door controllers at the No. 1 end streamlines operations since it is closest to the platform and ensures that the person responsible for safety and operation can easily access the controls while monitoring passenger movements. This placement facilitates timely responses to any issues that may arise during door operation and enhances overall safety measures on the train.

The other locations mentioned do not serve the same operational efficiency or safety requirements, making the No. 1 end the ideal position for the controllers.
