Der Flughafenbetreiber Aéroports de Paris hat die Verlängerung der LISA-Linie des CDGVAL-Metrosystems in Betrieb genommen. Liaison Interne Satellite Aérogare (LISA) ist eine vollautomati¬sche Metrolinie am Flughafen Charles de Gaulle in Paris. Diese Linie, die das Terminal 2E bereits mit dem Boarding-Satelliten S3 verbindet, wurde ohne Beeinträchtigung oder Unterbrechung des Betriebs bis zum neuen Satelliten S4 verlängert. Für die Streckenverlängerung um 300 Meter lieferte Siemens Rail Systems die Fahrzeuge (acht neue 26 Meter lange Zwei-Wagen-Züge vom Typ Val 208NG), die strecken- und zugseitigen automatischen Systeme sowie Aufrüstungen für die Betriebsleitzentrale.

CDGVAL / LISA PARIS CHARLES DE GAULLE INTERNATIONAL AIRPORT LINKS

Missions

setec acted as part of a consortium with a partner to provide Project Management Assistance (PMA) for the systems section, including interfaces with the Civil Engineering Department.
The tasks carried out by the consortium cover the design, production supervision, testing and delivery stages, as well as the preparation of Safety Files

CDGVAL is a public transport link connecting in only 8 minutes (compared to 25 minutes previously), the three Charles de Gaulle airport terminals, the Paris regional express network (RER), the high speed train stations (TGV) and the car parks, all distributed on five stations.
As a consortium partner, setec provided technical assistance to the Owner for the systems, including interfacing with the Civil Engineering. Setec took up the Project management since January 2003 as part of an on-site resident team comprising four engineers, one secretary and a draftman. The consortium’s assigned tasks comprised respectively the system complete design, manufacturing and construction supervision, testing and commissioning, along with the the safety case.

Specific project features:

  • Reuse of former automated people-mover APM infrastructures (CDGVAL),
  • Combined track, both anchored and resting on concrete sleeper blocks (CDGVAL),
  • Cross communications with concrete running tracks (5 CDGVAL, 1 LISA)
    Self-supporting Platform Screen Doors/ Doors controller at the end of each platform (26m CDGVAL, 52m LISA),
  • Various operation modes (temporary single track, shuttle, partial service),
  • Two-direction automated pilot (PADS)/ Digital safety systems,
    On-board real-time CCTV (WIFI / IP),
  • VAL 208 NG light automated rolling stock (7 for CDGVAL, 3 for LISA).

Expertises

Challenges

Complexity of operation modes and, consequently, the number of routes, led to implementation of digital two-direction automated pilots (PADS). That development relies on the use of a “B language” (formal language) guaranteeing that encoding of specifications does not create errors, and the use of an encoded single processor (digital safety system), with signature checking system, guaranteeing the correct code execution. That kind of approach, already used for Line 14 (Paris underground), is a first for the Light Automated system. THE CDGVAL line includes 5 line automated pilots and one automated pilot for maintenance garages.

Key figures

CDGVAL in figures: L3.3 km line / 5 stations, 5 stations, 24/7 operation.
LISA in figures: 600m of line mainly on viaduct/ 2 stations, 20/24 operation.
