These engines were designed specifically to work the Metropolitan's Aylesbury Extension. All of the motion was inside with 8" (203 mm) piston valves serving the cylinders. The boiler featured the square-shouldered Belpaire firebox. All had names in Metropolitan service: Lord Aberconway, Robert H. Selbie, Charles Jones, and Brill [named for the system's remotest station], respectively.

CitingAtkins, Philip. A tale of red 0-6-4Ts. Backtrack, 1998, 12, 37-8, steamindex says that these engines were not completedly successful, and suffered from cracked frames.

As the tall drivers indicate, these were designed for mixed traffic.Very little passenger work came their way, however. Moreover, they weren't regarded as very powerful and were seen as "non-standard" to boot.

All four were taken in by the LNER wheen that Grouping constituent absorbed the Metropolitan in 1937. Brill was withdrawn first in January 1943 and the class leader in May 1946. The other two survived Nationalization, but were retired in October 1948.
