GNRI Class JT

The Great Northern Railway (Ireland) JT class comprised six 2-4-2T locomotives, all built between 1895 and 1902 at their Dundalk Works. These were of a J. C. Park design, but introduced following his death. They were used on Dublin suburban services; then on branch lines, including operation of the Dundalk, Newry and Greenore Railway when taken over in 1933. Most were withdrawn shortly after 1955 between 1955 and 1957 but one remained passed to Córas Iompair Éireann (CIÉ) and remained in service until 1963.

History

The JT class comprised six 2-4-2T locomotives, all built between 1895 and 1902 at their Dundalk Works.[1] These were of a J. C. Park design, but introduced following his death. They were used on Dublin suburban services; then on branch lines, including operation of the Dundalk, Newry and Greenore Railway when taken over in 1933. Most were withdrawn between 1955 and 1957, but No. 91 (ex No. 13 Tulip) passed to Córas Iompair Éireann (CIÉ), and lasted until 1963.

Fleet details

They were subject to enlargement as batches were introduced, and rebuilt between 1917 and 1925 with improved 4-foot-2-inch (1.27 m) boilers and standard 16.5-by-22-inch (420 mm × 560 mm) cylinders. [2]
