That's an interesting reference, but you might warn Steven that the technical implementation of the locomotive is very, very wrong (read the discussion of the limitations and workarounds imposed by the software!)
For technical information, he might want to start (after looking at the usual steam locomotive Web sites) here:
http://steamcad.railfan.net/
and then find a copy of George Harlan's "Those Amazing Cab Forwards" (which, alas! usually suffers from the usual curse of out-of-print railroad books: the mercenary overpricing conspiracy by book dealers, so he might want to see if a Tomcat or similar search divulges a library, or interlibrary-loan opportunity available to him)

I tried to sell my two cents worth, but no one would give me a plug nickel for it.
I don't have a leg to stand on.
I am relatively familiar with the AC cab forwards from my reading and vintage film watching, what are the main differences in the later AC series? Specifically the angled cab face versions? Thanks...
