El Paso & Southwestern / Southern Pacific 4-8-2 "Mountain" Locomotives in the USA The first 28 "Mountains" on the Southern Pacific Lines were built by the American Locomotive Company and were delivered during 1923 and 1924.

these Cab Forwards came in several wheel arrangements including 2-8-8-2, 4-6-6-2, and 4-8-8-2. Although the crews initially complained about concerns that if they hit a gasoline truck at a grade crossing they would be right on top of it when it exploded.

The last Cab Forward in revenue service was 4-8-8-2 4211 which hauled freight from Oakland to Davis and then to Roseville with only a caboose on November 30th, 1956. In November, 1957 4274 was brought out of retirement to make the last run of a Cab Forward over Donner Pass from Sacramento to Sparks and back.

In 1939 the SP received 12 Yellowstones from Lima for use throughout the southern part of the SP system. Unlike the Cab Forwards, the class AC-9 locomotives were built as coal burners. They were later converted to burn oil.

Oct 19, 2018 · The Southern Pacific built a fleet of 4-8-2 Mountain type locomotives in the late 1920s in its Sacramento Shops. In 1930, the SP designed a locomotive similar to those Mountains that had a very large firebox (90.4 sq ft) and a four wheel trailing truck to support it.

Special equipment included the Franklin C-2 trailing truck booster and Worthington 4-B feed water heater capable of processing 7,200 US gallons (27,252 litres) per hour. HB Comstock contends that the SP 4-10-2s ran quite well.

These steam locomotives include a UP Big Boy, a N&W 2-8-8-2, an AT&SF 2-10-4, an SP 4-8-4, a C&O 2-8-4, and a NYC 4-8-2. If you like large steam and lots of them, this is a good place to visit. The museum exhibits are outdoors but mostly sheltered under roofs.

The "Mountain" 4-8-2 was a fast dual-service locomotive that was bought by many railroads in need of more motive power for the ever increasing weight of passenger trains and to compete for fast freight.

Schenectady promoted a brief vogue in large, two-cylinder cross-compound engines to several western railroads. These were the last in a series of such engines for the Souther Pacific and they were big and featured the long stroke usually found on 4-8-0s. They were almost immediately converted to oil-firing.

By 1916, the 2-8-2 "Mikado" type locomotive was replacing the "Consolidated" type throughout the country and the New York, Chicago & St. Louis was in need of new motive power and it follow the trend.
