Folks: I have a Legacy System that dates back to 2007 when Lionel first introduced it. I've been building a medium sized layout for some time. I have added the WiFi module; a couple of Block modules; 4 ASC's and a couple of Switch monitors. In addition I've installed three sensor tracks so far. Lately I've noticed erratic and intermittent problems, such as trains stopping and losing signal, hard to press buttons on the Cab-2, loss of sound. One time I had runaway trains. Fortunately, I have the expansion system and noticed that when using the newer controller most of the problems went away. I called Lionel and they honored the lifetime warranty and provided free shipping as well. I decided to send the base back as well, because not all the problems disappeared. I understand that the back log at Lionel service could be up to 8 weeks and I'm out of business I think. I considered purchasing a second Legacy system, but they are out of stock and not scheduled to arrive for months. I also have a TMCC system with a Cab-1. My question is: Is there a way to hook up the TMCC and the Legacy modules including sensor tracks? If not, what can I do in the meantime to run trains? What are my options? Thanks for any help.
