Long ago, I had an old slot car set, and it had a piece of track that had a railroad crossing for HO trains to cross the road.  Does anyone make anything like that?
I took an unholy delight in trying to nail the cars with the train if the racers didn't stop for me...

I'm looking at doing a layout in a very limited space, so I'm planning on a traction layout...besides, I like streetcars.

What is the turning radius of the Brill Trolley right out of the box, in both HO and N.  Can it be modified easily to turn in a tighter radius?  If so, how, and how tight?

Thanks!
