British Rail Class 13

The British Rail Class 13 was a class of diesel–electric shunting locomotive designed in 1965 to provide more powerful shunters for the Tinsley Marshalling Yard. Due to Tinsley's status as a hump yard, it was not possible to use a single locomotive owing to the risk of grounding. To achieve the required power, a pair of Class 08 shunters were permanently coupled in master and slave formation, with the slave unit having its cab removed and both units 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| Unit number | Master unit | Slave unit | Withdrawn | Fate | Notes | |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 | 13001 | D4190 | D4189 | January 1985 | Scrapped at BREL Swindon, May 1985 | |
| D4502 | 13002 | D4187 | D3697 | June 1981 | Scrapped at BREL Swindon, October 1982 | |
| D4500 | 13003 | D4188 | D3698 | January 1985 | Scrapped at BREL Doncaster, September 1986 |
Withdrawal
With the end of hump shunting at Tinsley the class became obsolete. The class's unique features were not required elsewhere and as such were withdrawn; 13 002 was withdrawn in 1981, with the remaining two locomotives scrapped with the closure of Tinsley hump in 1985.
