During World War II, the NCC was very short of shunting motive power and as no new engines were available, three engines were transferred from the Dundalk, Newry and Greenore Railway (DNGR). The DNGR engines were not a success and the NCC turned to the parent LMS for help. They offered two standard LMS Fowler Class 3F 0-6-0T locomotives. These engines had been developed from S. W. Johnson''s Midland Railway locomotives introduced in 1899. Johnson''s locomotives were originally built with round-topped fireboxes but they were all rebuilt with Belpaire fireboxes from 1919.
