Line 9 gets CBTC

01 Apr 2003

BARCELONA Line 9 is to be equipped for fully-automatic driverless operation using communications-based train control. On March 6 the regional government's construction authority GISA signed a €72·5m contract with a consortium of Siemens Transportation Systems and Invensys subsidiary Dimetronic SA.

Due to open in phases between 2005 and 2008, the 41·4 km line is expected to handle 90 million passengers a year. Trains will operate above each other on two decks in an innovative large-diameter single-bore tunnel (MR 02 p15).

Siemens, Dimetronic and Spanish telecommunications manufacturer EMTE will supply the train control equipment, interlockings and operations control centre. Siemens Vice-President Friedrich Smaxwill said the technology will draw on experience gained with Paris metro Line 14 and the CBTC development programme on the New York Subway. Data messages between the train and control centre will be handled using spread-spectrum radio as used by NYCT.
