response: 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.
original_response: 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.
history: I have got a new job! You know anything about conductors?
knowledge: 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.
