They passed to the London and North Eastern Railway at the grouping in 1923 and received the LNER classification J67.

[1] Eighty-nine locomotives were rebuilt between 1904 and 1921 with 180-pound-force-per-square-inch (1.24 MPa) boilers and increased water capacity.

Most were fitted with air brakes and used in suburban and branch line passenger service alongside the Class S56.

The 51 locomotives not rebuilt were used for shunting and working local goods trains.

They were sold to the War Department in October 1940,[4] where they were used on the Melbourne and Longmoor Military Railways.
