Re: Outside frame vs Inside frame

I think the problem of counterweights striking ice near the rail was unique to the WP&Y.
It had to do with springs in the roadbed causing solid ice to form on the outside of the rail which the counter weights sometimes struck causing a derailment.

I am not sure that it was completely accurate to blame the counterweights of the outside frame though.

If a spring can cause a solid ice buildup just outside of the rail, it probably could also cause solid ice build up just inside the rail as well, or all around the rail for that matter.
Any locomotive would like have problems when encountering solid ice buildups very near or around the rail.

Perhaps on the WP&Y the spring was in such a location that the ice build up only formed in a location as where the counter weights on the k-28's were an issue.

I imagine that the spring or springs are still there on the WP&Y and they likely still get ice buildups, but since they don't run in the winter now, it may not pose a problem.
