The '''NER Class R''' (later, '''LNER Class D20''') was a class of [[4-4-0]] [[steam locomotive]], designed by [[Wilson Worsdell]] for the [[North Eastern Railway (UK)|North Eastern Railway]]. They passed to the [[London and North Eastern Railway]] (LNER) in 1923. In 1936, some were rebuilt with long-travel [[piston valve (steam engine)|piston valve]]s and classified D20/2. The unrebuilt locomotives were re-classified D20/1.<br />
<br />
==Numbering==<br />
Forty-six D20/1 and three D20/2 locomotives passed to [[British Railways]] in 1948 and they were numbered 62340-62397 (with gaps).<br />
<br />
==Preservation==<br />
The last D20 was withdrawn in 1957 and none were preserved.<br />
