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 09 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, though following privatisation, in 1997 they have been distributed much further afield.
The originals became sub-class 09/0, when further locomotives from class 08 were modified in 1992 to form Classes 09/1 and 09/2.
The engine is an English Electric 6 cylinder, 4-stroke, 6KT. Traction motors are 2 x EE 506 motors with double reduction gear drive. The Main Generator is an EE 801.
There were variations, which were given the following TOPS design codes:

★ 09-0AX Original design; 50.4 te (502 kN); dual brakes

★ 09-0BA 51 te (510 kN), air brakes; RA6, knuckle couplings fitted [09003/11]

CLASSES 09/1 & 09/2

These locomotives were modified from Class 08 in 1992. TOPS numbers were 09 101 – 09 107 and 09 201 – 09 205. The design codes were as follows:

★ 09-1AX 110 V electrical system; 50.4 te (502 kN); dual brakes; formerly 20 mph (32 km/h) locomotive

★ 09-1BX 110 V electrical system; 50.4 te (502 kN); dual brakes; formerly 15 mph (24 km/h) locomotive

★ 09-1CX 110 V electrical system; 49 te (488 kN); dual brakes; fitted with knuckle couplings

★ 09-1EA 110 V electrical system; 51 te (508 kN); air brakes; RA6; fitted with knuckle couplings

★ 09-2AA 90 V electrical system; 49.6 te (494 kN); air brakes

★ 09-2BX 90 V electrical system; 50.5 te (503 kN); dual brakes

★ 09-2DA 90 V electrical system; 51 te (508 kN); air brakes; RA6; fitted with knuckle couplings
