What jobs could you do on a railway?

If you mean "On a Railway" is in at a station or on the locomotive itself, there are plenty of jobs. You could be the trains conductor, or the engineer (the person who controls the train). You could be a chef for the train, or a host/hostess. At a station, you could be the ticket salesman, or be on baggage assistance. There are far too many jobs that can be done to list them all in this thread, but I think you get the idea.
