Birmingham and Derby Junction Railway Locomotives comprised twelve passenger locomotives (ordered 1838) and two goods locomotives (ordered 1841).
When the Birmingham and Derby Junction Railway (B&DJR) amalgamated with the Midland Counties Railway and the North Midland Railway to form the Midland Railway (MR) in May 1844, the former B&DJR locomotives were given MR numbers; previously, they had been named, but not numbered.
Most were renumbered in February 1847.
First to be delivered in 1839 were those from Mather Dixon, with 'Tamworth' being used for the inaugural run.
These had 5 foot driving wheels.
