Rolling stock companies
Rolling stock companies (ROSCOs) own the actual trains that run on the rails. It is their job to work with the train operating and freight companies to determine the sorts of engines, carriage and trucks required to deliver the desired customer services.
ROSCOs also have a responsibility to help develop services by phasing out old and aged rolling stock to make way for modern, more convenient and safer trains.
ROSCOs either lease stock to train operating or the train building companies.
The companies listed below are builders of existing passenger trains for the British market.Last updated - 10 April 2014
