It's been decades since I cranked up my old Lionel trains so my question may sound dumb as I am years out of date. Thanks for your assistance.
- What is "fastrack?" I understand the difference between O and O27 gauge but fastrack is a new term to me.
- Lionel makes an accessory -- a crossing gate -- when the train approaches, a red-and-white striped arm drops down over the grade crossing and lights flash, just like on the big railroads. How do these work?? Do they come with a device that is tripped by the oncoming train or what? How do they turn off after the train has passed?
