Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 15312)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 73, pp. 319+. See also Mississippi Rails' entry at http://www.msrailroads.com/Tuskegee.htm . Works number was 58057 in October 1924.

101 was one of few new locomotives bought for the TRR. Its 1924 price was $21,250. The engine was destined for a line that had maximum grades of 2 1/2% and 18 degree (radii of 320 feet/97.6 metres).

After three decades of service on the TRR, the 101 was sold to the T R Miller Mill Company of Brewton, Ala in 1954. It next changed hands when collector Herbert Hansen of Union, IL bought the 101 in July 1969.

As of 2013, the locomotive was held as part of the Illinois Railroad Museum's collection.
