After years of waiting, I finally got back an MTH PS-1 steam engine I sent out for a PS-3 upgrade. Unfortunately, the engine doesn't function. At least, not properly.

When putting it on a DCS track, the engine is properly recognized by the TIU. It connects and properly starts up and shuts down. The bell, whistle, and lights all work. However, when applying forward or reverse motion, the engine remains still. Occasionally, it will slightly wiggle a tiny bit as if it is trying to move, but it immediately stops.

Additionally, when the engine is at 0 speed, there is a very loud whine that emits from the engine body (not the PS-3 speaker). At first I thought it was the smoke unit, but toggling smoke off with the DCS remote does not stop the whine sound.

Any assistance with this would be greatly appreciated. At the moment, the engine is unusable. Fortunately my repair shop didn't charge me for the work, but I still paid $350 CAD for the PS-3 upgrade kit.

Thanks!

To my knowledge MTH PS1 never had a 3 rail/2 rail switch. Back then 3 rail and 2 rail were completely separate. Perhaps the installer put in a DCS/DCC switch and it is set to DCC?

To me it sounds like it is something mechanical. Like something is stopping the motor from turning the wheels or something jammed in the gears. The whine you speak of sounds like the motor trying to turn but can't. I would not apply any more power to it-I would take it apart and make sure nothing is impeding the gears/motor/etc and that mechanically it is okay.

Just curious but why did it take years to get the upgrade done?

Good luck John!
