Notes

These enlarged versions of the basic W class showed the effects of superheating on the layout of tubes and flues; 4 arch tubes of 3 1/2" diameter supported the firebox's brick arch. They also had outside-frame trailing trucks as well as extended piston rods (ahead of the front of the cylinder) to decrease wear on the bottoms of the pistons and hence the cylinders. Compared to the Q-5 Pacific’s built by Brooks in 1920, these Mikes had slightly larger boilers, but less firebox heating surface.

Ten of this class later went to the Spokane, Portland & Seattle.

The Mikado engine was built to be sent to Japan,  They never made it it over there.  I don't know the reason why.
"Mikado" is the name generally assigned to the steam locomotives of the 2-8-2 wheel arrangement. The general, and reasonable assumption, is that this appellation stems from the construction of locomotives of this wheel arrangement by Baldwin in 1893. These locomotives were of the three foot six inch gauge, and were constructed for Nihon Tetsudo (Japan Railways), a private railway at the time. The class of these first locomotives was "Bt4/6". "B" was for "Baldwin", "t" meant "with tender", "4" stood for drivers, and "6" was for total axles. In 1906, 17 private railways, including Nihon Tetsudo became part of the Imperial Japanese Government Railways. It should be pointed out that after Pearl Harbor, in an excess of patriotic zeal, some railroads (most prominently the B&O and Union Pacific) renamed their locomotives of this wheel arrangement as "MacArthurs".   The Northern Pacific Railroad called them "Mikes"!
