Delaware, Lackawanna &Western 2-6-0 "Mogul" Type Locomotives

Class E-1/E-3 (Locobase 5718)

Data from Angus Sinclair, Twentieth Century Locomotives (New York: Railway and Locomotive Engineering, 1904), pp.536-538. See also DL&W 3 - 1938 locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Also see http://www.rr-fallenflags.org/el/loco/dlw-127.html (29 October 2003)

This was a series of conventional-cab Moguls built for light freight and passenger work. Schenectady supplied 29 (including 6 as E-8), Baldwin 6, Rogers 2. Slide valve travel was 5 1/2".

Many were superheated (See Locobase 5719).

Class E-2 (Locobase 5721)

Data from set of DL&W locomotive diagrams at http://www.rr-fallenflags.org/el/loco/dlw-127.html (29 October 2003) .

The only camelback Moguls to enter service with the Lackawanna. 18 came from Schenectady in 1903, 2 more from Rogers in 1906.

The class retired beginning in 1926 with the last leaving the line in 1934. None of these was superheated.

Class E-4/E-7/E-9 (Locobase 5717)

Data from set of DL&W locomotive diagrams at http://www.rr-fallenflags.org/el/loco/dlw-127.html (29 October 2003)

Drury (1993) explains that the line's Consolidations were slow drag-freight type and the Moguls satisfied the need for something faster. Rogers delivered 6 in 1906 and Schenectady added a pair in 1908.

Retirements began in 1930 and had been completed by 1937.

Class E-5/E-8/E-10/E-1- sup (Locobase 5719)

Data from set of DL&W locomotive diagrams at http://www.rr-fallenflags.org/el/loco/dlw-127.html (29 October 2003)

The Lackawanna superheated all of its 63"-drivered Moguls to a common standard. The firebox was unchanged and so were the weights. The slide valve casting received an "economy chest" that contained a piston-valve core.

Class E-9 (Locobase 5720)

Data from set of DL&W locomotive diagrams at http://www.rr-fallenflags.org/el/loco/dlw-127.html (29 October 2003)

Last pair of 57"-drivered Moguls (works #46164-46165) for the Lackawanna with a slightly larger heating surface and a little more weight on the drivers.

Retirements began in 1930 and had been completed by 1937.

Class none (Locobase 3284)

Interesting camelback with a surprisingly light look to it. The anthracite-burner had the large Wooten firebox at the back of which was a full windscreen for the fireman. The center cab has a steam dome squeezed between it and the tall pipe stack and large headlight. Perhaps the relatively small cylinders and raked pilot (cow-catcher) reduce the ungainliness.

According to a compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers were 2412-2413 (November 1898). No indication as to why there was a gap between the road numbers.
