Just purchased a Lionel 140 operating banjo signal, circa 1954-66. Expected Dec 24. Now, I have a slight problem! How do I connect this signal, to Lionel Fast Tracks?? This one, is used with the original Lionel tubular track, and snap on relay. Hoping to have it in use, even briefly, for Christmas train(s). Any help and/or information is much appreciated! Thanks.
