I just posted building instructions for my motorized railroad crossing lift-gates on BrickShelf: (URL) working on a set of instructions for my lighted "railroad crossing" sign next. I eventually hope to tie it all up with a formal write-up about (...) (23 years ago, 23-Feb-01, to lugnet.trains)

I've been trying to build a dual one (i.e. a gate on each side of the rails), but I keep having trouble keeping the sides in synch. If I use two motors, they seem to turn at slightly different rates so the gates don't line up after a while. I tried (...) (23 years ago, 25-Feb-01, to lugnet.trains)

(...) What I did on my lift bridge was used two motors but slaved them together with a geartrain and axle. That way they had to stay in synch but I wasn't asking one motor to keep both sides synched. ++Lar (23 years ago, 25-Feb-01, to lugnet.trains)
