Long Island 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class H-51a (Locobase 9484)

Data from Angus Sinclair (ed), "Baldwin Simple Consolidation for the Long Island Railroad," Railway and Locomotive Engineering, August 1903, p. 371. Works numbers were 22275-22276 in June 1903.

The article refers to a common alternate nickname for the camelback - the "Mother Hubbard". These low-drivered Consolidations were scrapped March 1928 (155) and December 1930 (154).


Class H51 (Locobase 2619)

Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899). Works numbers were 3101-3103 in December 1898. (Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.

If ever a locomotive design got hit in the face with an ugly stick, this Mother Hubbard Consoldation qualifies as a showpiece of unaesthetic ironmongery. Using a wide firebox to burn anthracite coal meant exiling the fireman to the rear deck under his own overhang. The engineer rode in a cab that bestrode the barrel over the drivers and ahead of the steam dome. With the fat barrel and small drivers to further disrupt any sense of proportion and grace, this camelback design must have been very serviceable because it couldn't depend on its looks.
