I have a 4-6-0 starter set controlled with the DCS Remote Commander. I brought the set to work to run around our office Christmas tree and it will run for 7-8 hours each weekday. My issue is the engine has had some runaway crashes over the last two weeks. Four times total and two of those instances were today, the most recent I was nearby when it began to take off and I was able to pull the plug before it careened of the track. The engine suddenly began to speed up rapidly with no user input, as if someone had opened up the theoretical throttle. The track is cleaned regularly and the receiver is about an inch from the track, so I believe signal and loss of power are not contributing factors. Any ideas on what could be the problem?

Top suspect is the drawbar and wiring or the tether for a PS/2 model. First stop is the actual MTH product number of the problem unit.

John,
Product number is 30-4216-1E. The set number is the same, sans “E”. I inspected the exterior portions of the drawbar but have not opened up the engine or tender to inspect the connections there. Nothing stood out to me while inspecting the exterior, connection seems solid.
The connector inside the locomotive that plugs into the drawbar is a frequent problem spot. Also, the tach reader could be an issue, maybe it's loose in the mount or a wire has broken and is just hanging on by a thread.

Thanks John, I won’t have the time to take a look at it until this weekend but now I know what to keep an eye out for. Will update with my findings.
Opening up the locomotive and tender did not reveal any glaring issues. Visually checked all the connections and they looked solid. Buttoned everything back up and tested on a conventional loop of track and it operated fine so the hunt for the problem continues.
