0-6-2

In Whyte notation, a 0-6-2 is a railroad steam locomotive that has six coupled driving wheels followed by two trailing wheels, with no leading wheels. Some locomotives of this arrangement had tenders while others carried their own coal and water tanks and were designated 0-6-2T.

Other equivalent classifications are:
UIC classification (also known as German classification and Italian classification): C1, French classification: 031,Turkish classification: 34,Swiss classification: 3/4.

United Kingdom

In the United Kingdom, various designs of locomotives featured the above wheel formation, most notably the suburban passenger GER Class L77 (LNER N7) and GNR Class N2 (LNER N2) locomotives. The former was designed for the Great Eastern Railway by Alfred John Hill and the latter for the Great Northern Railway by Sir Nigel Gresley. Many locomotives of this type were used in the South Wales Valleys by the Great Western Railway and its predecessors.

United States

In the United States however, 0-6-2 locomotives were largely 2-6-0 type locomotives that had been rebuilt with a larger firebox and therefore required greater weight distribution near their backs hence the leading wheels were moved in the position of trailing wheels. Nearly all of these units were sent to labor as switch locomotives or sent on branch lines.
