I thought I’d create this thread just for fun to show how the loco evolved from a modest little yard loco into a powerful giant.
First, it was the 0-8-0, but when a set of pilot wheels were added (0000o)it was renamed the Consolidation. From there, a set of trailing wheels were added (o0000o) and once again it was renamed the Mikado. A while later, yet another set of pilot wheels were added (o0000oo) and it became the Mountain type. But there were those out there that felt that the added pilot wheels would better serve it if they were located at the rear (oo0000o) so now it was called the Berkshire. The next thing you know someone added a second set of pilot wheels (oo0000oo) creating the Northern. But it didn’t stop there, and before it was over a second set of drive wheels were added creating (oo0000 0000oo) well, you know…
Enjoy.

the evolution of the 0-8-0, was it natural thing, or part of a premeditated plan by a highly intelligent being, hmm…guess it depends if your from Kansas or not. [}:)][;)]
On a serious note, it would be interesting to see an “evolutionary” (also sales and in-service lifetime) comparison to, say, the 0-4-0, 0-6-0, and 0-10-0 base models to see which had more variations, more total sales, and longer use life for the railroads. Though I’m not sure if there was any 0-4-0’s or 0-10-0’s base models. Would the original steamers be considered 0-4-0’s? I mean, say the 0-6-0. It had about the same evolutionary variants as the 0-8-0, but which sold more, the 6’s or the 8’s.
It would seem to me the 0-8-0 “family” had the most variations and sales, followed closely by the 0-6-0’s and it’s “cousins”. But I would expect to see the 0-4-0’s low in variations, but up there in sales and longevity, as the 4-4-0’s were the mainstay of almost every American railroad through most of the 1800’s, and, IIRC, many lasted into the early 1900’s. The 0-10-0’s would probably be low on all accounts, never hearing of an any kind of oo1010oo-type, at least not in the US.
hmmm…
