GP-10 - Model Railroader Magazine

For an engine that had several hundred made, and was used on over 80 different railroads, you'd think that SOMEBODY would come out with one in something other than mediocre brass. But nope, they haven't. Modelers get relatively oddball engines that virtually no one has ever seen, like Erie Builds and C-Liners, but a GP-10?

True, Kalso Shops are coming out with a CRAFTSMAN kit of a GP-10 (resin, photoetchings, and wire), but none of the big diesel manufacturers (Atlas, Athearn, Kato, Intermountain, heck Bachmann) has ever shown ANY interest in making a GP-10, and most have actually said flat out NO.

A real shame. Being a steam nut, I generally don't get worked up over dieseasels, but not having the option to buy a GP-10 is a real stupid thing in this hobby. We've got 3841 different F units on the market, but not the single most common shortline diesel in American history. That's a whole lotta smart...
