This is a Lionel Rio Grande SD-50 diesel engine model # 6-1822. The side of the box says Railsounds II & Liontech Command Reverse Unit. Underneath there are 2 switches Comm/Run & a switch for full railsounds or just the whistle. The instructions tell how to operate it in the conventional mode or in the command mode. So there is no guessing about it, this is a TMCC command control engine.
