I recently purchased a like new Atlas O Alco RS-3 with TMCC from a reputable dealer who stated that it had been checked out in Command and conventional modes and everything was fine. I am running MTH DCS and bought a Lionel TMCC Command base, special interface cable, etc. and hooked everything up as per instructions and was attempting to program it into the handheld controller. Even when the switch on the bottom is in "program" it takes off as soon as power is applied to the track. Anyone have any idea's ? Thanks in advance.
