Atlantic Coast Line 0-6-0 "Switcher" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 134/E (Locobase 11590)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 32; and ACL 10-1903 Classification of Engines supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange collection. Works numbers were 9874, 9877 in March 1889, 10237-10238.in September, 12155 in August 1891.

The ACL paid for six six-coupled switchers and had three delivered to the Wilmington & Weldon Railroad; the other three went to the North Eastern of South Carolina.. The 136 alsmost immediately entered service in 1890 on the Wilmington,.Columbia & Augusta as their 57.

All of these carriers gathered under the ACL tent in 1900. By 1903, an ACL classification record showed the Es fitted with thicker tires that added an inch to the drivers' oirignal 50" diameters. Boiler pressure settings of 130 psi (9 bar) in 1889 had risen 30 psi (2.07 bar) to 160 psi (11.03 bar).
