As a kid in the 70s,I swore I would be a monorail pilot, and ended up doing so for 8 years. These days, the operation is not quite the same, and soon they will move to the driver merely pushing a button to go, and it will be mostly automated.
I worked extra hours in alot of different areas, and it was interesting to see the different dynamics in different departments. CMs did not directly get to select where they wanted to work, and some areas were easier to get into than others.
