Who makes the TGV?
The prime contractor for almost all TGV trains is French rail manufacturer ALSTOM, formerly GEC-Alsthom. Of course a myriad of components that make up each trainset are manufactured by subcontractors such as Bombardier Transport, Faiveley, etc. Many more companies are involved in building the high speed lines and their associated equipment. It’s difficult for people outside the industry to keep track of who made what with all the corporate mergers, splits and associated complications.
