While the railway companies usually built their own wagons to their own designs the advantages of standardisation steadily became more advantageous. Not only in the ready availability of the increasingly robust and reliable RCH 'standard' wagons from private wagon builders. Parts for RCH 'standard' wagons would be available at repair depots far from the owners' system. A wagon becoming damaged, a 'cripple', could be repaired and returned to service quickly without needing to be returned to the owning company's workshops.
Following the end of the Great War the Great Northern Railway were given 50 7-plank wagons by the War Department as replacements for GNR wagons lost or damaged during the War. The GNR put these to use in locomotive coal service, all 50 entering LNER stock at the Grouping in 1922, being allocated LNER Diagram 4150.
