Hi guys!
I recently purchased an MTH genset switcher, I oiled it per instructions and put it on the tracks, it worked just fine for a little while. It did sit for a while while I got busy with other things.
When I started using it again, the rear wheels started to spin like they're not getting traction. At first it was just in certain parts of the track. Now when I placed it back on the track it just sits and spins with no movement. As part of my troubleshooting I did take a dry washcloth and went over all of my track and switches, parts of it were oily.
I am attaching a video of the problem, a picture of the underside. I also noticed a spot on my track where the wheels were spinning. Any help diagnosing the problem and potential fixes would be greatly appreciated!
