Willamette Iron &
All the Willamette locomotive truck castings listed fit the old style
of truck used on construction numbers 1 through 23. The wheel centers
and gears fit all the 3 truck locomotives regardless of truck style.
Construction numbers 1 through 17 used the same geared wheel on both
ends of the axle. The rest of the 3 truck engines used a plain wheel
center on the non geared side of the truck.
Many of these castings may be used for Shay locomotives.
