This may be a statement of the obvious, but ... I recently purchased a Proto 3 SW-1 (30-20149-1, MR) and finally have some track wired for DCS. I thought I'd test the track and the engine, but there is no DCS/DCC switch on the bottom of the engine. The on-line owners manual says there should be, but all I have is an empty slot. Probably needless to say, the engine remains dark and the DCS remote says there is no engine to be found. I'd appreciate any suggestions.
Thanks.
