Brian,

If you're thinking of Pennsy's 2D-F12 truck, then no. It's different.
It has the distinct V-9306 sideframe with room for only one leaf and
two coil springs, whereas the trucks on my list of users are all double-
truss sideframes with two coil springs to each side of the single leaf
spring. Pennsy did have double-truss 70-ton versions with a pair of
leaf springs surrounded by four coil springs.
