Bachmann's Narrow Gauge Mallet Even for HO scale?

[nachoman]

The prototype photo on your website of the Mallet going around the curve is of Baldwin's test of the Uintah 2-6-6-2. Uintah needed a powerful rod locomotive to traverse it's extremely tight curves (an 8-coupled locomotive would not work - even with blind flanges). Baldwin designed and built the 2-6-6-2s, and tested them around sharp curves at the factory before delivering them to the Uintah Railway. Considering the curves and grades of baxter pass - those locomotives were a remarkable design.
