Lehigh & New England 2-8-0 "Consolidation" Type Locomotives

Class E-12 (Locobase 2788)

Data from L&NE 8 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Classic "Mother Hubbard" (or camelback) layout with the engineer's cab straddling the boiler ahead of the wide Wootten anthracite-burning firebox. Like the E-13s (Locobase 6701), this pair had drivers tall enough for them to be used as road engines.

Class E-13 (Locobase 6701)

Data from L&NE 8 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This was the last class of "Mother Hubbard" (or camelback) Consolidations supplied to the L & NE. Little had changed in the basic design -- the grate area remained huge, the cab sat over the 2nd driving axle and between the two domes.

Class E-8 (Locobase 7049)

Data from L&NE 8 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Low drivers, camelback layout, big Wootten firebox -- all the elements of a typical helper on this Anthracite region bridge line.

Class E-9 (Locobase 7050)

Data from L&NE 8 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Very similar camelback to the two that landed on the L & NE three years earlier (Locobase 7049). A few minor changes included adding 3" to the tube length. When the engine was superheated, the area was just a bit less than the 25 & 27.

Class ES14 (Locobase 412)

Data from L&NE 8 - 1940 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Although their Wootten fireboxes were as wide as the earlier Mother Hubbards, these locomotives sported a conventional cab layout. The result was a pretty snug fit for the two crew, but it did rescue the fireman from his perilous perch on the footboard just ahead of a jouncing tender. Also, the firebox had both arch tubes (38 sq ft) and thermic syphons (109 sq ft) contributing to its considerable heating surface (the most direct heating surface in a superheated Consolidation).
