Willamette Iron & Steel

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.
