I was laying down some new Fastrack today, and during a test run my locomotive went around about twice, then stopped dead. Pull it back a few inches, and it would take off, then stop dead in the same spot as before.
In troubleshooting, I discovered that the track had no power half way around the loop!
Pulling the sections apart where the power stopped I noticed that the center pins were bent outward and away from each other, so they would not make good contact when the track was snapped together. I bent these pins toward each other so they visibly rubbed as the sections were clicked together. No more problems.
Is this common?
