I bought this crossing gate set new along with the Scott's Odd's -n- Ends MTR 12V AC DC ready relay for activation.I placed them on my layout for a mock up but the gates never actually became part of the finished railroad, becoming extras instead. One of the crossing gates was bench tested for operation and worked fine. The crossing gates are in like new condition with the original box. The relay is new and unopened. The hobby shop I bought the crossing gates from recommended the relay as an alternative to infrared activation. Relay directions include specific MTH crossing gate set wiring.
