The British Rail Class 13 was a type of diesel-electric shunting locomotive. The type was designed in 1965 because of the need to provide more powerful shunters for the Tinsley Marshalling Yard. Because of Tinsley's status as a hump yard, it was not possible to use a single locomotive owing to the risk of grounding. So, to achieve the required power, a pair of Class 08 shunters were permanently coupled in 'master and slave' formation, with the slave unit having had its cab removed. Both units were then ballasted to improve traction. Initially coupled cab-to-cab, it was found more practical to couple master nose to slave cab.

Units[]

Three pairs were formed as follows:

Unit number Master unit Slave unit Withdrawn Fate Notes
Original TOPS
D4501 13 001 D4190 D4189 January 1985 Scrapped at BREL Swindon, May 1985 [1]
D4502 13 002 D4187 D3697 June 1981 Scrapped at BREL Swindon, October 1982 [2]
D4500 13 003 D4188 D3698 January 1985 Scrapped at BREL Doncaster, September 1986 [3]
13 003 at Tinsley TMD

Withdrawal[]

With the end of hump shunting at Tinsley the class became obsolete. The unique qualities of the locomotives were not required elsewhere and so withdrawal was inevitable; 13 002 was withdrawn in 1981, with the remaining two locomotives going with the closure of Tinsley hump in 1985. None of this unusual class survives.[4]
