Montpelier & Wells River 2-6-0 "Mogul" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 11 (Locobase 14068)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 45, p. 168. Works number was 33394 in May 1909.

Covering the 38 miles from Vermont's capital city to the railroad town on the Connecticut river, the M & WR also operated a 5-mile spur to Barre and its big granite-quarrying business. Construction began in 1870 and opened in two sections on 15 September and 24 November 1873. (The last train over the line ran 83 years later on 15 November 1956.)

The two anchor cities differed in elevation by only 62 feet (18 metres) with Wells River at 461 feet (141 metres) and Montpelier at 523 feet (159 metres). Between the two, however, lay such stops as Groton Pond at 1,078 feet (329 metres) and the aptly named Summit cresting at 1,443 feet (440 metres).
