The H&BR Class F1 (LNER Class N11) was a class of 0-6-2T steam locomotives of the Hull and Barnsley Railway. The locomotives were part of a batch built by Kitson & Co. for the Lancashire, Derbyshire and East Coast Railway (LD&ECR), but the order was cancelled because the LD&ECR was unable to pay for them.
