I have two MTH Rail King O scale 3 over 3 block signal Model # 30-11024. Originally it was activated with a Lionel I-Tad, but that item finally failed to work. Can this signal work with an insulated segment of track or must I find another I Tad ? I cannot find a wiring diagram. Also, will other sensors other than I - Tads work with these. Look forward to your responses.
