The Great Northern Railway (GNR) Class O2 was a class of three-cylinder 2-8-0 steam locomotive designed by Nigel Gresley for freight work and built by the GNR from 1921. Sir Herbert Nigel Gresley ( 19 June, 1876 &ndash 5 April, 1941) was one of Britain's most famous Steam locomotive engineers The Whyte notation for classifying Steam locomotives by Wheel arrangement was devised by Frederick Methvan Whyte Other classification schemes like Rail gauge is the distance between the inner sides of the two parallel rails that make up a railway track. On a Steam locomotive, a driving wheel is a powered Wheel which is driven by the Locomotive 's Pistons (or Turbine, in the A cylinder is the central working part of a Reciprocating engine, the space in which a Piston travels Tractive Effort (abbr TE is the pulling force exerted normally by a Locomotive, though the term could also be used for anything else that pulls a load Class (locomotive refers to a group of locomotives built to a common design for a single railroad The Great Northern Railway (GNR was a British railway company established by the London & York Railway Act of 1846 In the Whyte notation, a 2-8-0 is a Railroad Steam locomotive that has a single-axle Leading truck followed by four powered Driving axles A steam locomotive is a Locomotive powered by Steam. The term usually refers to its use on Railways but can also refer to a "road locomotive" Sir Herbert Nigel Gresley ( 19 June, 1876 &ndash 5 April, 1941) was one of Britain's most famous Steam locomotive engineers Further examples were built by the London and North Eastern Railway (LNER) from 1924.

Sub-classes
The LNER created four sub-classes: [1]
- O2/1, Introduced 1921. Development of experimental Gresley GNR 3-cylinder locomotive (LNER 3921). Subsequently rebuilt with side-window cab and reduced boiler mountings.
- O2/2, Introduced 1924. Development of O2/1 with detail differences.
- O2/3, Introduced 1932. Development of O2/2 with side-window cab and reduced boiler mountings.
- O2/4, Introduced 1943. Rebuilt with 100A (B1 type) boiler and smokebox extended backwards. The London and North Eastern Railway (LNER Thompson Class B1 is a class of steam locomotive designed for medium mixed traffic work A smokebox is one of the major basic parts of a steam Locomotive.
