Sumpter Valley Mallet #251 -- UintahIt might sound like a double header, but the two Uintah Mallets, and later the Sumpter Valley Mallets, are actually single, articulated, double-boiler locomotives. Unusual for North America. Listen as BigSound™ uses its double-chuff feature to reproduce the distinctive in-and-out-of-phase effect for this unique, two-of-a-kind engine. |
