@GG14449 posted:Having some bad engine luck this weekend. I wanted to replace the broken engine on the Christmas layout and have an old K-line switcher I bought six months ago. It was working when I put it away but now when I add power it just lights up, buzzes and shakes in place. Any ideas?
It looks like this might be one of the unusual single-motored S-2 switchers from a DC set... did it run with a power supply you got with it or some other power pack?
