Funny you should ask. About five minutes ago, I took it out back and ran it
around my tightest radius curve, which is about 7 feet. It handled that fine, so
the minimum is somewhere between four and seven feet. (Is four feet radius
right for LGB 1500? I think so.) I'll be sure to include a suitable caveat on the
conversion kit labels. I don't have much of a feel for how many people still
have those ridiculously tight curves, but I'm sure I'll hear from them all if I don't
state it in big red letters. It's one of the laws of physics, I think.
Baldwin actually built a loco of this type with blind second drivers. The theory
was that, since it's effectively a six-coupled engine, the "middle" driver didn't
have to be flanged. Turned out not to work so well in practice....
