Geared steam locomotive
A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
NER Class X
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. The steam reversing gear was removed again between 1941 and 1947.
In 1929, No. 1656 was moved to the newly built Whitemoor Yard at March, Cambridgeshire. In 1932, this locomotive was replaced by Nos. 1355 and 1358. 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. In 1936, No. 1355 moved to King's Cross to shunt the engine shed for seven weeks, before joining No. 1358 in Doncaster. These two locomotives were scrapped at Doncaster in 1937. The remaining T1s continued to work coal trains at various docks and marshalling yards throughout North East England. After World War II, coal exports never returned to their pre-war levels. Hence, many of the T1s moved to other sheds for heavy shunting duties.
