I have a vintage Lionel train set that was purchased in 1952. I played with it has a child, but after that it was boxed up for 40 years. I have set up about a year ago and with a little care the train runs fine. I have four 022 Lionel switches in my layout. I have recently installed two UCS tracks. They are from the time period as the train set.
The UCS tracks will uncouple the cars when the train is in motion. When I put the train in neutral over the UCS track it will not uncouple the cars even if I put the transformer at full power. One of the UCS tracks I have wired to have for fixed voltage and the other is not. Both operate in the same manner at this time. I have six clip-ons around the layout. I have checked for loose wires from the clip-ons and the switches and can find none.
Because the UCS tracks operate when the train is running and do not otherwise, I think I have a power issue, but I am not sure. I have a KW transformer to power the track and I have the switches being powered by a 1033 transformer. I am attaching pictures of the transformers and the UCS track that is wired for fixed voltage. The fixed voltage is wired to the 14 volt connection on the KW.
Thanks for your help.
