Will most train crew know the tracks they drive on right and left and go there several times. And how far away from there home base will they travel as well? Also how many places or directions do they go from home base? And how long are they usually gone for?
The crews usually qualify on the route they drive.
In my area, one of the routes is between Los Angeles and San Luis Obispo, a distance of about 220 miles. Another route is between Los Angeles and Bakersfield about 185 miles. The crews around here will travel on both lines. A third direction is Los Angeles to West Colton and the fourth is Los Angeles to Long Beach. A crew member can go to all four places.
Usually they go one direction one day and about 8 or 9 hours after they arrive at the destination they'll turn around and come back, then go where there next assignment takes them.
