TheLD&ECR class A (LNER Class N6) was a class of0-6-2Tsteam locomotives of theLancashire, Derbyshire and East Coast Railway. An initial batch of eight was ordered and built in 1895. An order for 15 more was placed in 1899 but five of these were not delivered because the LD&ECR was unable to pay for them. The undelivered locomotives were re-sold byKitson & Co. to theHull and Barnsley Railway and becameH&BR Class F1 (LNER Class N11).[1] There are some detail differences between the LD&ECR class A and the H&BR Class F1 but these were the result of later modifications.
