Who operates the doors in the MATC system?

The correct answer is that the train engineer operates the doors in the MATC system. The train engineer is responsible for a variety of critical functions, including the operation of the train itself and certain onboard systems. In many transit systems, the engineer is typically in charge of door operations to ensure safety and efficiency during boarding and alighting processes.

Having the train engineer manage the door operations allows for streamlined communication and coordination when the train is stopping at stations. This role is crucial, as it allows the engineer to control the timing of door openings and closings based on the train's speed and position, ensuring that passengers can board and exit safely without any unnecessary delays that could occur if managed separately.

Other potential roles such as the train conductor, trainmaster, or maintenance crew have distinct responsibilities that do not typically include direct control of the train's door operations. For example, conductors may assist with passenger interactions and fare collection, but they are generally not the ones directly operating the doors on many systems. The trainmaster often oversees the broader operations and schedules of train services, while the maintenance crew focuses on the upkeep and repair of the trains and infrastructure.
