RE: [CBQ] Question On CBQ in Billings

Disc main drivers, as applied to the M-2/M-2-A 2-10-2s created less pounding on the rails, which was a major drawback of these plodding freight haulers.  Thus they were allowed a higher speed.

I have been working on a timetable scanning project and in the process I was reading the Special Instructions for the Yellowstone Divn mainline as it relates to the 5th Sub between Billings and Laurel. The instructions say that the CBQ class M-2 with disc wheels is allowed to go 40 MPH while "other CB&Q freight trains" cannot exceed 35 MPH. Why the difference is speed when it relates to class of engine?
