29 scrapped, 21 rebuilt as "Humpty-Dumpties", 60 rebuilt as 4-4-0
The GER Class T19 was a class of 2-4-0steamtender locomotives designed by James Holden for the Great Eastern Railway. Some were later rebuilt with larger boilers while others were rebuilt with both larger boilers and a 4-4-0 wheel arrangement. Unusually, both the 2-4-0 and 4-4-0 rebuilds were classified as GER Class T19 Rebuilt. All the 2-4-0s had been withdrawn by 1920 so only the 4-4-0s passed to the London and North Eastern Railway in 1923 and these became the LNER Class D13.
Standard 2-4-0s
The T19s was similar to the WorsdellClass G14, but had a slightly larger boiler. One hundred and ten locomotives were constructed. They had 18-by-24-inch (457 mm × 610 mm) cylinders and the last ten had 160-pound-force-per-square-inch (1.10 MPa) boilers, but the remainder were gradually fitted with two-ring boilers.
Between 1902 and 1904, twenty-nine were rebuilt with new boilers with Belpaire fireboxes. With their small tenders, and a dome well-forward on the first ring, they looked front-heavy, and gained the nickname Humpty Dumpties. In fact they were so front heavy that they were never considered for superheating.[2] They were withdrawn between 1913 and 1920.
Between 1905 and 1908 sixty were rebuilt as 4-4-0 tender engines with the same new Belpaire boilers. The first ten re-used the bogies from Class G16[4] 4-4-0s, while the other re-used the rear bogie from withdrawn Class E10[5] 0-4-4T locomotives.[6] Superheaters began to be fitted from 1913,[7] and all those still in service in 1926 had been so fitted.
Two were withdrawn in 1922, and the remaining fifty-eight passed to the LNER at the 1923 grouping. The LNER Classified them as Class D13, and added 7000 to their Great Eastern number. They were initially repainted in the LNER passenger green livery, but from 1928, repaints were in black with red lining.[7] Withdrawals continued steadily, until in 1944, the last survivor was withdrawn.[8] See also (Ahrons 1951).
