Yep, usually each cab is used a few times per day. If you bring a train out of shop, you're in cab 1. If you bring a train into shop, you're in cab 6. If you're driving Epcot or Express, you're in cab 1. If you're driving resorts, you're in cab 6. If you bring a resort train to shop, you switch to cab 1 at the Contemporary, then switch back to cab 6 after going through the switch and ending up at the MK. From there its cab 6 all the way back to shop. Really the only time you move the train in the opposite direction of which cab you're in is to re-align your stop if you over-shoot the station, and in that scenario you have an observer on the ground or at the station or other location to verify beamway behind the train is clear before reversing. The name of the game is operating the train from the same cab as the direction of travel.
