Service history[edit]


They were introduced in 1900 and had inside cylinders and piston valves operated by Stephenson valve gear. Forty of these new Class D engines were delivered in 1900-01, twenty each from Neilson and Company and Sharp, Stewart and Company.[1] At grouping they became LNER class J83.


The class were highly successful in service, with only three failing to complete one million miles (1,600,000 km) during their lifetime. One locomotive, No. 9830, managed to complete two million miles (3,200,000 km).[1]


The engines were commonly seen across the entire North British Railway network, and were the second largest class of tank engines on the railway, after the NBR A class.



Numbering[edit]


On the NBR they were numbered in a sequence commencing with 795 (and are sometimes referenced as 795 class engines). A total of 40 locomotives were built, all but one of which came into British Railways (BR) ownership at nationalisation in 1948. BR numbers were 68442-68481.[2]



Withdrawal[edit]


One locomotive was withdrawn in 1947, pre-nationalisation, but otherwise the class were gradually displaced by diesel shunters during the 1950s, with the last withdrawn in 1962. All members of the class were scrapped, and there is no surviving example in preservation.
