Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 78, p. 148. Works numbers were 58469 in June 1925.
Tackling 4% grades and getting around 26 degree (radii of 220 feet) curves, this bi-fuel (coal and wood) Consolidation was rated for both passenger and freight service. (Locobase admires the candor behind the admission that speed would never be the primary virtue of a ride on the Salvador.)
The specification contains this guidance about following tradition in building this locomotive: "Detail parts as far as practicable to be interchangeable with those of 10 28 D 120 and 121, built for this same company in 1910 [Locobase 13678]; however, this is not to restrict Engineering Department in designing a thoroughly modern locomotive." Locobase suspects much of the difference lay in materials that permitted a higher boiler pressure and the extensive use of electric welding.
Grates and smokebox netting suitable for wood fuel would be installed by Baldwin. Coal grates and netting would be supplied as part of Extra Order No 564.
