Locomotives of the North Eastern Railway

Edward Fletcher (1854–1883)

Edward Fletcher was inherited from the York, Newcastle and Berwick Railway, one of the NER's constituents. There was very little standardization during his term of office, and only a few types are listed here.

Alexander McDonnell (1883–1884)

Alexander McDonnell moved from the Great Southern and Western Railway of Ireland. However his policies proved unpopular with the drivers and he resigned after only one year in office.

Locomotive Committee (1884–1885)

Between A. McDonnell and T. W. Worsdell there was an interval during which the office was covered by a Locomotive Committee. The Locomotive Committee was chaired by Henry Tennant.

Thomas William Worsdell (1885–1890)

T. W. Worsdell was an enthusiast for compounding and many of his designs used the two-cylinder system of August von Borries, usually in conjunction with simple-expansion versions of the same engines for comparison. The compounds were mostly rebuilt as simple-expansion engines by his brother and successor Wilson Worsdell.

He introduced the system of class designations, starting with "A" for the first, and so on, and then adding a digit for later developments of each. This system was reorganized somewhat in 1914.

Wilson Worsdell (1890–1910)

Wilson Worsdell was the brother of his predecessor.

Vincent Raven (1910–1922)

Vincent Raven was the last Chief Mechanical Engineer of the North Eastern Railway
