The Turbot bogie ballast wagon was a development from the earlier Bogie Bolster E wagon, which was manufactured in the 1960s and was intended for the transfer of steel. The wagon, however, after a number of years in use was found to be too short for the continuation of its intended role, but it was found that if a low sided three door body was added, then this new wagon would to be suitable for transporting ballast. The wagon was nicknamed "Turbot" and was TOPS classified as YCV bogie ballast wagon. Over 1,000 Turbot wagons were rebuilt by BR Shildon and RFS Engineering at Doncaster between 1982 and 1988 and continued into service until 2002. Turbot wagons have also been modified for use by London Underground.
