Signalling, ATC and ATS equipments of the Lisbon Metro Line D.
Commissioning: May 1998
This project included the design, manufacturing, testing, installation,
commissioning, training and warranty for:
- the signalling system including signals, point machines, track
circuits,
- train control movements (ATP and ATO),
- supervision (ATS)
This system, which uses the principles of the
SACEM system installed
on the Paris RER, is implemented on a safety computer based on High Speed line
technology. It significantly increases line capacity and improves safety
conditions.
The new train location system, which uses Doppler radar technology, allows a
train stopping precision of +/-15 cm in stations.
In total, 73 trains are equipped to ensure the transport of passengers with a
90-second headway.
