Finsishing up an article for the November-December issue of The B&O
Modeler on Class W-1 and subclass hoppers and came across some odd
trucks. I've uploaded a detail photo in the STMFC files section
titled "B&O 334344 Class W-1A Truck Detail.JPG":

Anyone know the type of this truck? Thanks in advance!
Ben, it's an arch bar truck with a Pilcher trussed side frame. See the
1922 Car Builders' Cyclopedia, p. 628.

I don't have that CBC to compare the photos, but according to an
article in Railway Age (April 12, 1924) it describes the use of arch
bar trucks designed by Edwin C. Washburn, assistant to the president
of the B&O. The trucks were placed on new cars ordered in 1922 with
capacities of 40-ton, 55-ton and 70-ton. The class W-1a were rebuilt
by various car builders ~1922 for the B&O so there is a high
probability that the trucks used were of this Washburn design. The
illustrations of the side frame in the RA article appear very similar
to the one in the photo posted by Ben.
