CDGVAL is a free shuttle rail service at Paris-Charles de Gaulle Airport (CDG), using the VAL (English: automatic light vehicle) driverless, rubber-tyred people mover technology.
The first line, which connects the three airport terminals, train stations, and parking lots, opened on 4 April 2007.
Aéroports de Paris (ADP) planned to overhaul the transport system within the airport perimeter by introducing an internal train link.
Deemed unreliable and incapable of meeting availability targets, ADP were forced to consider alternatives despite the amount already invested which had attained nearly 150 million Euros of state funds.
In June 1999 the project was abandoned so ADP had to invest urgently in order to renew its fleet of ageing coaches and maintain road service.
Building on the original project, CDGVAL largely followed the SK path while adapting existing infrastructure to allow transit of automatic metro-type equipment.
Terminal 2 has an RER-B platform directly underneath it; this station also handles the high-speed TGV, and Eurostar.
