Middle Tennessee/SLSF 4-6-0 "Ten-Wheeler" Locomotives in the USA

Class 25 (Locobase 8550)

Data from SL&SF All Time Loco Diagrams HS Pub supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also DeGolyer, Volume 36, p. 43. Works numbers were 36168 in February 1911.

The Baldwin spec for this particular engine took special care to note that the water tanks were 19 miles (30.6 km) apart, the ruling grade was 3.3%, minimum curve radius bent to 18 degrees, rails weighed 70 lb/yard (35 kg/metre), and the turntable could handle up to 60-ft (18.29 m) engine-tender combinations. Somewhere along the line of ownerships shown below, the engine received a set of Southern valve gear, that remained with it at least until its arrival on the Frisco.

This single Ten-wheeler went on the MT in February 1911 and operated there until the road was sold to the Nashville-Frankford line, which electrified the tracks and sold the 25 to locomotive rebuilder/reseller Southern Iron & Equipment. Locobase can't help but think that the turnaround sale to the Gainesville & Northwestern was perhaps a bit hasty when he considers the equally rapid return of the item to the SI&E. A year later in November 1925, SI & E found a buyer in the Jonesboro, Lake City & Eastern, which was immediately bought by the Frisco.

After serving the road for another 14 years, the 75 was "dismissed from service" in July 1939.
