Kansas City Southern 2-10-4 "Texas" Locomotives in the USA

The Kansas City Southern Railroad ran from Kansas City, 786 miles south, to Port Arthur, TX on the Gulf Coast. In need of new motive power in the late 1930s KCS turned to the Lima Locomotive Company and purchased ten "Texas" type locomotives in 1937.

Five of them (road numbers 900 through 904) were oil burners and the other five (road numbers 905 through 909) burned coal. These Class J locomotives had 70" diameter drivers, 27" x 34" cylinders, a 310 psi boiler pressure and a tractive effort of 93,302 pounds. The oil burners weighed 509,000 pounds and the coal burners weighed 514,000 pounds.

All ten of the 2-10-4s were retired in 1952 and 1953 and were scrapped by 1954.

Class J (Locobase 97)

Data from tables in 1930 Locomotive Cyclopedia, supplemented by KCS 1942 - 2 Locomotive Diagrams supplied in May 2005 by Allen Stanley. (Many thanks to Chris Hohl for his 22 September 2017 email reporting unlikely boiler pressure values for 177 entries. A Locobase macro caused the error .) Lima works numbers 7660-7669.

Five engines (900-904) burned oil, 5 (905-909) burned coal. (Don G. Campbell (NRHS Bulletin, 1964) speculates that splitting the fuel may have been done "to satisfy both the coal and petroleum industries along the line."). Oil-burner tenders carried 21,700 gal (82,135 litres) of water and 4,500 gallons (17,033 litres) of oil; these weighed 348,000 lb (157,850 kg) loaded. The engine's boiler began work with 46,000 lb (20,865 kg) or approximately 5,400 US gallons (20,439 litres) of water.

The firebox layout was relatively plain, using only 56 sq ft (5.2 sq m) of arch tubes to supplement the heating surface area provided by the basic furnace and combustion chamber.

Although originally intended for the Shreveport-KC run, World War II delayed upgrading the rail south of De Queen, Ark. to the 127-lb/yard (63.5 kg/metre) standard, so these engines worked on the Northern Division only. During World War II, these engines stepped in to pull troop trains and were able to meet passenger train schedules. Although not quite attaining the tonnage ratings of the road's "Big Mallies," these engines represented superpower in its most striking form.
