Invensys Rail Dimetronic has started operating its Rail 9000 automatic train supervision (ATS) system on the São Paulo Metro Line 8 in Brazil, owned and operated by Companhia Paulista de Trens Metropolitanos (CPTM).
The Rail 9000 ATS incorporates a centralised traffic control (CTC) system, SIREI intelligent regulation control and maintenance assistance.
The new system provides automatic supervision, regulation and maintenance of Line 8 from an Operational Control Center (OCC).
The system will also monitor, control and regulate the line’s current relay-based interlockings before the introduction of a new interlocking system based on the Westrace microprocessor, also designed by Invensys Rail.
Invensys said that the Rail 9000 system simplifies the migration from electromechanical technology to a modern railway signalling system.
Now that the deployment of the ATS system is complete, Invensys will work on commissioning the Sirius communication-based train control (CBTC) system on Line 8, as well as other lines on the metro system.
The Sirius CBTC system is being installed to work in parallel with the existing signalling systems until its installation and commissioning is complete.
Invensys Rail Dimetronic secured a contract from CPTM in 2009 to install and commission the Sirius CBTC system onboard and trackside on lines 8, 10 and 11 of the São Paulo Metro, along with Westrace electronic interlockings, electric drive switchers and LED signals.
São Paulo Metro Line 8, also called the Diamond Line, has a length of 35 km and 20 stations, while Line 10 runs 35km with 15 stations and Line 11 spans 37km and 12 stations.
