The NER Class X (LNER Class T1) was a class of 4-8-0T tank locomotive designed by Wilson Worsdell for the North Eastern Railway.[1] They were intended for use as powerful shunting engines to arrange and move coal wagons for loading into ships.[1] In total 15 were built, 10 by the NER between 1909 and 1910, and a further five in 1925 by the London and North Eastern Railway (LNER).[1] They had three cylinders with divided drive: the inside cylinder driving the leading axle, the outside cylinders driving the centre.[2]

Overview

The reversing gear was originally mechanical, but was replaced on all but two of the locomotives (nos. 1355/8) by steam-operated reversing gear between 1932 and 1934.[3] The steam reversing gear was removed again between 1941 and 1947.[3] In 1929, No. 1656 was moved to the newly built Whitemoor Yard at March, Cambridgeshire.[4] In 1932, this locomotive was replaced by Nos. 1355 and 1358.[4] Whitemoor preferred the ex-GCR 0-8-4T (LNER Class S1) for hump shunting, so in 1934 No 1358 was moved to Doncaster, and No. 1355 to Mexborough.[4] In 1936, No. 1355 moved to King's Cross to shunt the engine shed for seven weeks, before joining No. 1358 in Doncaster.[4] These two locomotives were scrapped at Doncaster in 1937.[4] The remaining T1s continued to work coal trains at various docks and marshalling yards throughout North East England.[4] After World War II, coal exports never returned to their pre-war levels.[5] Hence, many of the T1s moved to other sheds for heavy shunting duties.[5]

Numbering

On the North Eastern Railway the first ten locomotives were numbered 1350–9; these numbers were retained following the formation of the LNER on 1 January 1923. The five built in 1925 were given LNER numbers 1656–60.[6] In 1946, the thirteen remaining locomotives were renumbered 9910–22; these all passed to British Railways in 1948, being renumbered 69910-69922 between 1948 and 1951.[7]

Withdrawal

Two T1s were withdrawn in 1937, and the remainder were withdrawn between 1955 and 1961. No examples have been preserved.[5]
