HELP 2 railers I'm a 3 rail guy but I got some flyer 2 rail trains and track and what I need `I think is a #690 lock on to connect the transformer to the track, also on the back of the transformer it says "base", "7-16V", and "16V" which 2 terminals do I use? It is a model 1 1/2 B transformer. Thanks, I do know that you can't make a reverse loop without some fancy footwork.
Use the 7-16 and base posts
690 yes, but some L "lock-ons" (that's NOT an AF term for the item) have two sets of "flanges" and will fit AF track.
