I have a Lionel Southern Pacific AC-9 2-8-8-4 w/Odyssey. It has long been my favorite engine, but it has developed a problem. I run both TMCC and Legacy, and when I attempt to power up the engine, it takes off like a bullet with spinning tires going full boar, etc. I have to hit the halt button or turn the power lever down to save the engine from launching into space.
The engine has done this on occasion in the past but usually shutting down power and starting again fixes the issue. Now, however, I can't seem to break the cycle. The Odyssey switch is off (as I have always run it this way). I have tried reprogramming it and the problem persists in both TMCC and Legacy mode.
I just ran down to check whether it functions conventionally. It powers up but does not move- that can't be good!
Nothing out of the ordinary happened to the locomotive recently. I admit I am not an expert with the whole Odyssey feature. It truly is my favorite engine and I hope this is a problem that others have dealt with successfully.
Thanks in advance for ANY advice on correcting the issue.
