CBTC Sao Paulo Commuter Lines
Invensys Rail Dimetronic leads the consortium that is modernising and improving the signalling and ATC systems of the suburban lines 8, 10 and 11 of São Paulo, Brazil.
Invensys Rail Dimetronic is installing its SIRIUS system, a Communication Based Train Control (CBTC) type system, in the three suburban lines together with its rolling material and WESTRACE electronic interlockings, electric drive switchers and LED signals.
In order to minimise the service disruption during the improvement works, the new system will be designed and installed so that it can operate alongside the existing signalling system until it is completely installed and operational. This working methodology has already been used by Invensys Rail in other subways in different parts of the world, proving the company’s ability to carry out successfully complex projects within the agreed deadlines and, at the same time, minimising the impact on the service for the passengers.
The three suburban lines belong and are operated by the Companhia Paulista de Trens Metropolitanos (CPTM). Line 8 has a length of 35 km and has 20 stations; line 10 has a 37 km layout with 16 stations and line 11 has a total extension of 50 km and 16 stations. Altogether these three lines provide a service of 136 trains plus maintenance vehicles for more than one million passengers per weekday.
