Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 85. See description of the Texas Southeastern in Locobase 12821. Works number was 26971 in December 1905.
This Mogul's boiler pressure setting looked like an unlikely outlier, but Baldwin's spec shows the safety valve settings as 220 (15.2 bar), 240 (16.55 bar), and 260 psi (17.8 bar) and an inked-in tractive effort of 16,830 lb (74.7 kN). This high pressure, combined with the small boiler and low cylinder volume, made it something of a pocket rocket. Indeed, Locobase wonders how long the TSE--owned by Southern Pine & Lumber--operated the 6 at that relatively intense level given the use of slide valves.
The 6 never changed its road number as it migrated to Temple Lumber's operation by 1912. Some rosters report that Temple sold the 6 to the Lufkin, Hemphill & Gulf.
