Hi, Just bought an old (very old) Liliput electric loco on eBay. Looks great, runs great on a straight track, but quits on a curve . Both trucks are very stiff in side to side and vertical motion. I think this is the problem and I could cure IF I could get the shell off and get at the works. But, I can not see how the shell comes off; there are no screws or tabs that I can see! Is there a Liliput expert out there who could give me some tips? Thanks in advance. Dai
