North British class D
London & North Eastern class J83
Great Britain 1900 40 produced
In 1900, the North British Railway received 20 0-6-0 tank locomotives from Neilson, which were intended for shunting services and local freight trains. 20 more from Sharp followed in 1901. They were in service throughout the North British network and all came to the LNER in 1923 as class J83. Only one locomotive was retired prior to the formation of British Railways, in 1947. The rest were retired by 1962. 37 of the 40 locomotives reached the one million mile mark within their service life, and one even managed two millions.
