I have a beautiful example of the 3356 Horse Car Corral and Car, that I am determined to use on my layout, and am in need of some assistance. The corral itself has two pivoting arms on it, that go under the outer rail of regular straight track, in order to keep correctly positioned relative to the car ramps. However, since it appears you need to use a UCS section to power the car, the arms cannot line up under the section of UCS track. Is there something I am missing? Does it NOT need a UCS track? TYIA!
