It depends if you’re going for assistant conductor or locomotive engineer. For engineers, you can’t really run on your own until you’re marked up so you’re studying, running trains, working all sorts of odd hours in various locations. It’s a straight shot, the minute you’re marked up, you’re fully qualified and you still have to do annual block training classes. For conductors, it’s different as you’ll be in school for about 11-12 weeks, start working as an assistant conductor doing on the job training and in a year, they’ll call you back to get the conductor qualifications which means more studying and exams.
