The Great Western Railway (GWR) 1600 Class is a class of 0-6-0 pannier tank steam locomotive designed for light branch lines, short-distance freight transfers and shunting duties.

The 1600 Class was a pure GWR design but all 70 were built by the Western Region of British Railways.

Two locomotives (1646 and 1649) were transferred to the Scottish Region in 1957 and 1958 to operate the Dornoch Light Railway.

In 1992 it was sold to its present home on the Kent and East Sussex Railway, and is currently operational after its latest overhaul was completed in 2016.
