The tram not giving familiarity is deliberate, as it runs on rails so there's no way that you being familiar with riding it would increase its speed. To make this more immediately obvious, in v0.4 it's been replaced with an event. You perform a very short action to start the tram, then there's a timed event during which you're free to perform other actions within the tram (but no longer have access to actions at your point of departure).
