Class 102 (Locobase 14154)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 48, p. 281. See also the Chris Cravens, "BARTLETT WESTERN RAILWAY," Handbook of Texas Online (http://www.tshaonline.org/handbook/online/articles/eqb02), accessed May 15, 2012. Published by the Texas State Historical Association. Works number was 40536 in September 1913.

The BW was a 23-mile shortline that was chartered on 17 June 1911 to succeed the Bartlett-Florence Railway. According to Chris Cravens's account, the four stations between Bartlett (about 55 miles north of Austin) and Florence were named for the Four Apostles: St. Matthew, St. Mark, St. Luke, and St. John.

Although successful during its first two decades, it wasn't an especially well-built line. Cravens notes that "cars jumped the tracks so often that the line became known as the 'Bullfrog line'". The 102 was the only locomotive on the line in 1926. A fall in cotton prices and the onset of the Great Depression doomed the line and it was abandoned on 11 October 1935.
