What have you found so far?
Senior Conductors work solely on the Class 170 routes and can work all or part of the 170 network (Cardiff-Nottingham, Brum-Stansted).
You'll be responsible for opening and closing doors, passenger safety, revenue checks, passenger assistance, assisting the driver if needed, evacuating the train if needed, as well as other duties.
You'll need to be good at customer service, safety focused, teamwork, working by yourself, punctual etc.
Hope this helps.
