Re: K-36 and K-37

The simple mechanics of placing the frames outside of the drive wheels makes the engine wider, allowing the larger boiler to set lower in the frame and be more stable.  The distance across the tops of the outside edges of the  frames on an outside frame 3' gauge locomotive is around  59".  By the time you add the driving boxes and counterwieghts and/or cranks to the end of the axles you are wider than a similar sized standard gauge locomotive.  A standard gauge engine is around 48" across the tops of the frames.

Makes no difference if it is a 2-8-0 or a 2-8-2,  an outside frame 3' gauge engine is wider than a comparable standard gauge machine.

Examples of the D&RGW K-36 and K-37 both exist today. . The K37's are converted standard gauge locomotives.

I know the 2-8-0's are pretty wide, but what about the C-21's and the C-25?  Were they also wider?
Sure wish they would have survived, not may outside-frame 20=-8-0's are around anymore.  Is the WPY loco that Stathi is rebuilding a 2-8-0?

Most outside framed 3 foot gauge locomotives are actually wider than similar sized standard gauge ones -  by about a foot.  K27's are wider than a K36-37.
