Several projects were suggested: an extension of Paris Métro Line 7, an additional branch of the RER B, and an extension of the RER C. Ultimately, in December 1987, authorities opted for the construction of a shuttle line from the airport to Antony station on the RER B line using the Véhicule Automatique Léger (VAL) technology developed by Matra for the Lille Metro which opened in 1983. The project was seen (and criticized) as a showcase project for Matra who was hoping to sell VAL systems to cities across the world.
