Elgin, Joliet & Eastern 2-8-0 "Consolidation" Type Locomotives

Class 500 (Locobase 7295)

See data from EJ&E 11 - 1938 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Baldwin supplied this class to the EJ & E in batches of 4 (1892), 2 (1893), and 2 (1895). 508 arrived in 1896 and was identical.

The diagram notes that they were discarded on 11-15-1924.

Class 510 (Locobase 7870)

See data from EJ&E 1924 Locomotive Data supplied in May 2005 by Allen Stanley from his extensive collection.

Class 518 (Locobase 7871)

See data from EJ&E 1924 Locomotive Data supplied in May 2005 by Allen Stanley from his extensive collection.

Class 528 (Locobase 7872)

See data from EJ&E 1924 Locomotive Data supplied in May 2005 by Allen Stanley from his extensive collection.

These were very similar to the Baldwins the EJ & E had purchased a year or two earlier (see Locobase 7871). But the boiler held more, smaller-diameter tubes which resulted in a higher total evaporative heating surface area.

Class A-2 - saturated (Locobase 7297)

See data from EJ&E 11 - 1938 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. For roster information, see "The EJ&E Photo Archive" database, specifically the roster pages http://eje.railfan.net/page_steam_roster.html (accessed 23 Feb 2006).

Class A-2 - superheated (Locobase 7296)

See data from EJ&E 11 - 1938 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This superheated set of Consolidations is the updated portion of a class that covered road numbers 549-602. The result was a pretty potent set of 2-8-0s. Even so, all of the A-2s were converted to 0-8-0s, most of them in the late 1920s and early 1930s.
