Pacific Coast / Pullman Company 2-6-0 "Mogul" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 12079)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p 4. Works number was 13732 in September 1893.

The independent PC Rwy began as a 10-mile link between San Luis Obispo and Avila Beach (and Port Harford) on the coast. It would eventually cover 76 miles from Port Harford to Los Olivos. Even after the Southern Pacific entered SLO in 1901, the PC Rwy continued as an agricultural and mineral road, but with decreasing revenue. One branch was electrified.

The 101 was scrapped in 1924. The last segment of the line was abandoned in 1941.

Class 16 (Locobase 14115)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 43, p. 189. See WikiProject Trains ICC Valuations page on the Pullman Company at Works number was 38623 in October 1912.

The Pullman Company had 23 miles of track in its yard tracks in Buffalo, N. Y., Calumet (Chicago), Ill., Richmond, Calif., St. Louis, Mo., and Wilmington, Del. Its famous works at Pullman near Chicago also included considerable rail mileage.

This middle-sized Mogul useful switcher to all those heavy passenger cars, although Locobase cannot pinpoint where the engine was used. The 16 had to negotiate curves of up to 30 degrees (193 feet/59 metres in radius) while rolling on relatively heavy 80-85 lb/yard (40-42.5 kg/metre) rail.
