My beloved B&O 0-6-0 steam engine took a jump off my elevated loop, hit the table top, fell off the table, hit a "footrest" beam on the bottom of the table, then finally hit the floor. Ugly stuff although thankfully more cosmetic than mechanical - and I can easily fix the busted up coal load, minor paint dings, etc. Still, it wasn't pretty.
Since some of the mechanical issues were a bit beyond my abilities, I took my engine to my LHS this morning. I looked at my bill and saw this and had to laugh! This is the problem description - thankfully it was fixed while I waited.
Tip for the future - don't lean over the controls and accidentally bump the throttle "wide open"!!!!
