I am familiar with Lionel's traditional "O" gauge insulated track section, as well as GG track having all 3 rails insulated.
I recently decided to do away with GG and Ross switches on my Christmas layout and go with FasTrack (I'll pass on explanations unless there is interest). I purchased a batch of track from my LHS, including a couple of insulated track sections. What puzzles me is the track appears to have no way to put an insulating pin in each end of an outside rail. All connections are conductive (or appears to be). I asked my LHS owner about it and he was as in the dark as I was. We turned over a standard section and compared it to the insulated one. Only observable difference we noticed was the insulated section was missing a metal strip that connects the two outside rails. So, can someone tell me how the insulated section works without an insulating pin in each end of an outside rail? I plan on passing on your wisdom to my LHS owner, who, by the way, is outstanding at customer service.
