That's some very nice stuff in those links, thanks for posting!
Modelling wrecked locomotives is always something I've had a real interest in doing. The only one I have done so far was an "accidental" (perhaps more prototypical that way
) wreck. I posted photos to this older thread:
http://railroad.net/forums/viewtopic.php?f=32&t=70204 Dropping a loco is not the ideal way to wreck it...that one I decided to patch, so it has given me a kind of neat looking "repaired" loco.
I have an old Dash 9 cab and and old U-boat body (sans-trucks) both sitting around at the moment. I think one of them (or both) might well end up getting a wreck treatment some time in the future. I love locomotive servicing facilities, and would like to model one in the future, and having a wrecked locomotive sitting on a service track would be a very neat addition.
