Re: Outside frame vs Inside frame

Another point about outside frame locomotives. Placement of the counterweights makes a difference in snowy country.

Look at the early Baldwin outside frame 2-8-0s built for the Colorado Fuel & Iron Co's Crystal River railroad 101 - 103 (later D&RGW 360, 261, 275) Silverton Gladstone & Northerly 34, and Deadwood Central 3, 5, and 6. All of these 2-8-0s had the counterweights on the driver centers, and only the cranks on the ends of the axles. This would present no major difficulties to the WP&Y in the winter. In fact, they had some outside frame 4-6-0s built this way.

Later, Baldwin cast the counterweight as part of the crank - as is the case on WP&Y 69, the D&RGW K-36s and many outside frame 2-8-0s built for IRCA, like 40 and 44. I believe the D&RG Class 125 (later D&RGW K-27 class) had counterweights on both the driver centers and the cranks. The K-28s had the counterweights for the number 3 axle equipped with the counterweight cast integrally with the crank; the other axles all appear to have the counterweights cast in the driver centers.
