Atlantic Coast Line 2-6-0 "Mogul" Type Locomotives

Class 134 (Locobase 11590)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University - their catalogue Vol 15, p. 32. Works number was 9871 in March 1889.

This single Eight-wheeler gained some cylinder volume by extending its stroke 2" past the usual for a 17" cylinder. Only a few 4-4-0s would adopt a similar measure, most of the rest increasing the cylinder diameter an inch or more.

Class D1 (Locobase 7351)

Data from ACL 1913 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

These Moguls were bought by the ACL of South Carolina from Rogers at the same time as the 4-4-0s shown in Locobase 7350. Most of the dimensions are similar and vary primarily to accommodate a 2-6-0 arrangement rather than the Eight-wheeler. The steam dome sits proudly over the firebox crown sheet while the equally ornate sand dome hovers over the leading driven axle.

Class G (Locobase 7353)

Data from ACL 1930 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Four out of the six Moguls supplied by Baldwin in February 1896 went to the Wilmington & Weldon, a principal constituent of the ACL when it formed four years later. The other 2 were delivered to the Norfolk & Carolina, which connected a W & W branch from Tarboro, NC to Pinner's Point, Va, which served Hampton Roads.
