Alton & Southern 0-10-0 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 14 (Locobase 13993)

Data from Alt&Sou 1937 Locomotive Diagram book supplied in May 2005 by Allen. Works number was 67150 in November 1930. See also DeGolyer, Vol 80, pp. 610+. (Thanks to Chris Hohl for correcting the valve gear ID and for noting the tender booster tractive effort.) Works number was 61570 in November 1930.

Big, all-adhesion switcher for this mineral road's transfer service and the last 0-10-0 Baldwin would build. It was bought for the A&S by the Aluminum Company of America (Alcoa's).

The 14 was delivered with a two-unit thermic syphon setup; later the firebox heating surface area included 108 sq ft (10 sq m) in four Nicholson thermic syphons. Another aid to providing plenty of hot steam was the superheater's share of combined heating surface area, which was quite large . Piston valves measured 14" (356 mm) in diameter.

The front truck of the tender was converted to a booster; photographs show the coupled axles (as well as aluminized cylinders, steps, and most of the boiler). Indeed, Alcoa's interest in promoting aluminum for load-bearing applications led to the specification of aluminum in many components from grab irons to side rods.
