Drivers make safety announcements as well as announce stops. They control when doors open and close and watch that passengers are safely in or out of the cars. Drivers control how long the train is at a stop and try to stay on schedule. When breakdowns or emergencies occur, drivers contact the dispatcher. They may have to evacuate the passengers from the train.
Streetcar operators are similar to subway train operators.
The main difference is that streetcars travel on the surface, not underground. Operators must observe street signals as well as watch the movement of cars. They collect fares and issue change and transfers. They also answer questions from passengers about fares, schedules, and routes. Subway Train Drivers is a specialty of Railway Transportation Workers.
