ANSALDO STS CBTC SYSTEMS :ANSALDO STS CBTC SYSTEMS


CBTC System: Train Separation :CBTC System: Train Separation CC ZC Radio Radio ATS 1. CC calculates the position of the train using track side beacons and the train’s odometer 2.The position is sent by radio to the zone controller (ZC) 3.ZC (based on the information received from all trains) calculates the MAL (X) and sends it to the vehicles. ZC also sends the position of all trains to the ATS to be displayed 4. The CC calculates its braking curve so that the MAL is never exceeded ATS = Automatic Train Supervision ZC = Zone Controller CC = Carborne Controller MAL = Moving Authority Limit AP = Access Point


CBTC System: Train Separation :CBTC System: Train Separation ZC ATS ATS = Automatic Train Supervision ZC = Zone Controller CC = Carborne Controller MAL = Moving Authority Limit AP = Access Point 4. The CC calculates its braking curve so that the MAL is never exceeded


CBTC System: Interlocking :CBTC System: Interlocking CC ZC Radio Radio ATS 1.The position of the switch is controlled by the IXL that sends the status to the ZC 2.ZC (based on route of the train and the position of the switch) sends the MAL to the vehicle and the status of the switch to the ATS IXL 3. If needed the CC calculates its braking curve so the MAL is never exceeded ATS = Automatic Train Supervision ZC = Zone Controller CC = Carborne Controller MAL = Moving Authority Limit IXL = Interlocking

CBTC System: Unequipped/failed train :CC ZC Radio Radio ATS IXL 1.The unequipped train does not communicate but it occupies the track circuits 2.The IXL detects the track circuit occupation and sends this information to the ZC 3.The ZC places the MAL behind the last track circuit occupied and sends it to the equipped train and to the ATS 4. The CC calculates its braking curve based on the MAL CBTC System: Unequipped/failed train

Examples of CBTC Systems :Examples of CBTC Systems Paris/RATP (OURAGAN Project) Shenyang Metro (China)


Shenyang (China)New Line :Shenyang (China)New Line Line 1 28 km Double track 22 Stations 1 Depot 1 1.25 km of test track 1 OCC 23 Vehicles Started March 2007 Ansaldo STS participation: Responsible for all the signaling engineering (ATP+ATO) Provider of equipment (ZC, CC, Radio, ATS And MicroLok® II) Radio communication based on 802.11 (WiFi) Test runs and validation on site in 2009 Revenue service April 2010


Paris, OURAGAN CBTCOverlay on an existing line :Paris, OURAGAN CBTCOverlay on an existing line 6 Lines planned Started in March 2004 Ansaldo STS participation Responsible for the integrations of all the signaling systems for the first line, Line 3 Provider of the wayside equipment Zone Controller and maintenance system DCS or (FRONTAM) Responsible for producing all interoperability technical specifications Communications via Radio Site tests and validation of interoperability on going on the Test Track (in tunnel) Revenue service planned for November 2009


Final Considerations :Final Considerations The Ansaldo STS CBTC system can be applied to new lines as well as to lines that need renovation as an overlay system, without service interruption Ansaldo STS CBTC system is based on open interface and communication architectures Ansaldo STS has extensive experience in delivering, maintaining and operating “turn key” UTO systems
