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.

==History== 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.

==Numbers== Originally numbered 2511–2520, in the Midland's [[Locomotives of the Midland Railway#Numbering and classification|1907 renumbering scheme]] the Schenectadies became No. 2230–2239, in the same order.

==Withdrawal== Being non-standard, they had a short life and were all withdrawn between March 1912 and August 1915 and later scrapped.{{sfnp|Baxter|1982a|p=172}}
