Moscow, Camden & San Augustine 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 5587)

Data comes from the Texas Transportation Museum website (20 June 2003), which also styles itself as the Longhorn & Western Railroad. See also DeGolyer, Volume 36, p. 65 and George C. Werner, "MOSCOW, CAMDEN AND SAN AUGUSTINE RAILROAD," Handbook of Texas Online (, accessed July 21, 2013. Published by the Texas State Historical Association.. Works number was 35816 in January 1911.

Wholly owned by the WT Carter & Brother lumber company, the MC & SA ran for 6.8 miles (11 km) in St Augustine county in East Texas. This little Consolidation served the railway as a switcher for decades, burning (at least at first) pine slabs. 1929 saw the engine's conversion from wood-burning to oil-firing.

Out of service in 1956 with 90,000 miles (144,900 km) on its boiler. The museum comments that this locomotive will probably never run again because it has a riveted boiler, which were outlawed in Bexar County in 1925. Georgetown, Texas volunteers had planned to restore it, but the engine was delivered to the TTM in 1984.
