Train guard

A conductor (American and Canadian English) or guard (Commonwealth English) is a train crew member responsible for operational and safety duties that do not involve actual operation of the train. The conductor title is most common in North American railway operations, but the role is common worldwide under various job titles. In Commonwealth English, a conductor is only responsible for selling tickets.

The responsibilities of a conductor in North America and of a guard in Commonwealth English typically include the following:

Some rapid transit systems employ conductors to make announcements and open and close doors—as opposed to a train operator performing those duties. The conductor often stays in the center of the train where they can best view the platform. While advances in automation allow most transit systems to use one person train operation (OPTO), a few, such as the New York City Subway, Toronto Transit Commission and Sydney Trains continue to employ conductors.

Conductor is also a crew member in some bus, trolleybus or tram operations.

In North America, the conductor manages a freight, passenger, or other types of train, and directly supervises the train crew, which can include a brakeman, flagman, ticket collector, assistant conductor, and on board service personnel. All crew members work under the conductor. The conductor, engineer, and additional engine crew members (fireman, pilot engineer) share responsibility for safe and efficient train operation and adherence to railway rules and procedures. On some railroads, union contracts specify that conductors must progress to engineer.

Other conductors duties include:

Passenger trains may employ one or more assistant conductors who assist the conductor and engineer in the safe and prompt movement of the train, to share the workload, and accept delegated responsibility. If a train crew's route, or tour of duty, exceeds a single shift, or conflicts with a legal or contractual limit on the number of work hours, more than one crew may be assigned, each with its own conductor. Onboard service crew members on passenger trains normally remain on duty for the entire run, including assigned meal and sleep breaks.
