Gorton Works constructed the first ten locomotives of this class in 1911. They were built to replace the Atlantic tank engines of GCR Classe 9K and Class 9L on the developing suburban traffic on the Great Central/Great Western joint line out of London Marylebone.
A further six locos were constructed in 1912 and five more followed in 1917.
The class was selected after grouping by Gresley to fulfil an urgent need for large passenger tank locomotives in the Middlesbrough area of the North East of England. Thirteen locomotives were built by Hawthorn Leslie in 1925-26. The new locomotives, designated Class A5/2, differed from the original Robinson version by way of a reduced height chimney, dome and cab roof. Coal and water capacity was also reduced.
Following nationalisation the GCR engines were classified as Class A5/1, while the Hawthorn Leslie locomotives became Class A5/2.
All Class A5/1 locos were allocated to Neasden at Nationalisation in 1948.
The Gresley engines had all been withdrawn by 1958, but the original Robinson engines (except one) lasted until 1960.
The first loco withdrawn by the LNER was No. 5447 in 1942 from ??? shed.
