Are you referring to the train crew member? Conductors are responsible for the aspects of operation and safety of the train that don't involve actually operating it.
Hmm you must be pretty brave to take a job without knowing the job description. As a conductor you will be a train crew member responsible for operational and safety duties that do not involve actual operation of the train.
I have got a new job! You know anything about conductors?
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.
