Wheeling & Lake Erie 4-4-2 "Atlantic" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class E-1 (Locobase 7884)

Data from W&LE 8 - 1923 & 10 1924 Locomotive Diagram books supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 30916-30921.

This batch of Atlantics represented typical high-speed engines of the time. Compared to other US 4-4-2s, these had relatively generous firebox areas, smaller than average grates, and about average evaporative heating surface area. The driving and engine wheelbases ran toward the top of the range while the adhesion and engine weights came in around the median. Likewise, tractive effort also met the median.
