Hi - no one knows how to disassemble? I'm always very wary, although I know the trick about putting filings in stripped screw holes and using a soldering iron to "melt" new threads ... the info
"these engines have LED's but they are driven from the control system circuit boards, not directly from track power" - is helpful, I'll see if I can't pull from track power, also am considering drilling a hole to mount a bright LED headlight .. would be tricky - has anyone changed these number boards - I think mine doesn't let light shine through ...
