The British Rail Class 09 is a class of 0-6-0 diesel locomotive designed primarily for shunting but also short distance freight trips along branch lines.[1] For this reason, though similar to the existing Class 08 shunting locomotives, Class 09s were re-geared to give a maximum top speed of 27.5 mph (44 km/h) at the expense of a lower tractive effort. They originally operated in the Southern Region of British Railways, though following privatisation in 1997 they have been distributed much farther afield.
