I have a OO train set received as a gift from 1980. Iím in the process of cleaning & lubricating. I watched a how to video on YouTube the other day, then got to work on my own train. I noticed the cover of the ring field motor isnít properly attached as a clip on the right hand side has broken off. Iím still having issues with some of my engines on my layout, so I figured Iíd check the trains first. Iím thinking of using foam tape at the top of the motor, to keep everything together. The motor still runs after all these years.
