Jonathan - In memory of the USRA Class M-3 locomotives, here are two
more Lines West images (inserted and attached) showing No. 6301 in Denver,
CO, on September 4, 1940 and sister No. 6305 in the deadline at the Denver Shops
on July 3, 1953:
Both locomotives were sold for scrap in August 1953, victims of shiny new
EMD Geeps, SDs and Covered Wagons. This might be telling, but to my knowledge
not a single M-3 was modernized with lightweight running gear, as were a number
of the Class M-2-A locomotives. In any event, not a single M Class locomotive
(including the Class M-4 2-10-4 type) was preserved. Best Regards - Louis

John,
thank you for recalling what the Beardstown folk said regarding the different
classes of 2-10-2. It sounds like adhesion and/or tractive effort plus
familiarity (or unfamiliarity with Southern valve gear) were major factors in
the Q's preference.
Louis,
thanks for the great photos! That one at Bushnell really gives you a sense of
what they were up against. It's interesting that what seems like a relatively
small difference in engine weight and driver size could make that much
difference in engine perforormance. But I guess at the limits of tonnage you
really start to appreciate it.
Jonathan
