No, it is not it. The idea is that the living module or RV is still occupied during the travel unlike the motorail, where passengers are traveling in separate passenger cars. Car shuttle trains where passengers stay inside the vehicle also do not offer connection of utilities to RV. And my idea goes further where living module is disconnected from engine/wheels platform when loaded on the train (if the design is standardized similarly to containers, you can get new one at the destination, so the train carries less weight).
