Yes, one does have to be very aware especially if your trike is wearing narrower tyres (e.g. my ICE Sprint). Those with wider touring or balloon tyres should be fine (wife's Hase Kettwiesel).
Good point! One of the reasons I first mounted 55mm wide tires on my commuter Sprint and later even switched to 24" front wheels with 55-507 tires, where the six train tracks and two flap bridges I had to cross on my commute.
They are also one of the main reasons I choose to mount the widest tires possible (40mm) in my velomobile.

Especially when its wet and the train tracks cross the street at an angle, I'll rather take the trike, than any two wheeler. With a trike its just inconvenient to cross train tracks, but with a two wheeler it can be really dangerous.
