Atlantic Coast Line 2-8-0 "Consolidation" Type Locomotives

Class L (Locobase 7679)

Data from the ACL-3 1946 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Consolidations made up only a small part of all of the locomotives operated by the ACL and these were the first to be procured by the railroad in the 20th century. They had a relatively small grate.

Apparently, none of these was superheated. Several were converted to switch engines by the end of the teens. The whole class was retired in 1939-1942.

Class L-1-S/L-2-S (Locobase 7680)

Data from the ACL-3 1946 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These light Consolidations completed the rather small holding of 2-8-0s on the ACL. The three L-1 appeared in 1905 with the four L-2 following in 1911. Not long after they entered service, all 7 were superheated to the same standard. All had the "modern" steam chest.

Although present in small numbers and possessing relatively small boilers for their cylinder volumes, they showed staying power in the niche in which they operated and saw out steam on the ACL as they were scrapped in 1951-1955.
