This is one of the 2-6-6-2s.

Thanks - I really wasn't sure what the later ones had under the smokebox. It makes sense to only run a two wheeled truck, since it doesn't have any "pilot" responsibilities, and the weight on the smokebox end does not require it.
As long as we are talking big articulated engines, up here in our neck of the woods, the Great Northern had their share. Most were used further east, on the Iron Range or in the Rockies, but some did make the haul up and over our Cascade range.
Their penultimate version was the R2, a 2-8-8-2. Some were made in their own shops, some came from Baldwin. They claimed one of the highest tractive efforts of any locomotive:
GN also ran one of the better "Northern" class, or 4-8-4 locomotives, in their "S" class. Beautiful locomotives, with their green boilers and silver smoke boxes. They had a pretty distinctive pilot truck as well.
