The Murhpy was pretty much 4 axle territory and in the days of steam nothing bigger than a Connie or Mike. Gus, thanks I will try to get some more up soon.
Interesting. What is the reasoning?
In parts of Canada, branch lines were the territory of 6 axel locos because the per axel loading on the lighter rail was lower than if they'd sent the smaller, but 4-axelled locos. e.g. RSC-2
On the steam side, CNR restricted use of 2-8-0s on southern Ontario branch lines because they were heavier than the light Pacifics they had.
