Thank you for the quick replys and the help. I'll try cleaning Percy this weekend. The trackwork is good and clean so I will concentrate to the engine.

Hello, I'm new the the forum and need some advice. My son's Percy has stopped working and I am unable to figure out how to dis-assemble him to see what the problem is.  We are also considering going to DCC and I was wondering if anyone else has any sugesstions.  Thanks in advance for any help!
