I just had my worst train wreck to night. Whiles backing a 7 car train through a switch at the edge of the layout the lead engine derailed (a 2035 that I had just purchased and repaired) and tilted precariously taking the tender with it and a dummy Milwaukee Road GP9 with it. Yes, substantial damage. Broken marker light, twisted tender tongue, and broken mounting lugs and truck mounting pin on the dummy unit.
I can repair everything, I think. "Man" am I disappointed.
Edge guards are going to be installed. I cannot imagined how I would feel if a really prized locomotive took the big dump on the concrete.
