This engine was commissioned in 1917 during Woodrow Wilson's presidency. After World War I the USRA 2-6-6-2
Mallet was used for commerce related endeavors. The first Mallet was manufactured by Schenectory Works to
the Chesapeake & Ohio. The larger cylinders in the front received their steam from the rear cylinders as
exhaust steam. This ensured the proper amount of thrust steam and on the protype was significantly larger
than the rear set of cylinders. Steam was carried by the external piping which can easily been seen on the
model.
Specifications: Total weight = 448,000 lbs. Drivers=358,000 lbs. Tractive effort compound=80,000 lbs.
Single tractive effort=96,000 lbs. Prototype had low and high pressure cyclinders( not modeled as such).
Comments on the BRASS Model: This model was purchased from a re-seller and has no modifications since it's
purchase. It as an original pittman OFM motor. The model runs quite well with only the
rear cylinders powered. I used this model in part to reconstruct the basket case version.
Note:** 1966-1967 - GEM imported Akane shows this same model with brake shoes, prototypical blarge and small cylinders
,both sections powered by OFM, and connected with rubber tubing as in the 2-8-8-2 USRA.
