Midland Railway 2511 Class

The Midland Railway 2511 Class was a class of 2-6-0 steam locomotives built by the Schenectady Locomotive Works in the United States, as a supplemental order to the 2501 Class built by Baldwin that same year. As with that class, the Midland had turned to American locomotive builders, as their own Derby Works had reached capacity, and was unable to produce additional engines at the time, and many British locomotive builders were recovering from an 1897-1898 labor dispute over working hours.

HistoryEdit

The engines were designed and built with more consideration to British practice than the 2501 class had been. While the engines retained some distinct features of American practice, such as the use of bar frames, they had cleaner lines, with sandboxes placed below the boilers, as well as three-axle rigid tenders.

NumbersEdit

Originally Nos 2511–2520, in the Midland's 1907 renumbering scheme, the Schenectadies became Nos 2230–2239, in the same order.

WithdrawalEdit

Being non-standard, they had a short life and were all withdrawn between March 1913 and August 1915 and later scrapped.[1]
