1 Dedicated Line: MRS Logística Brazil MRS s CBTC Project SIACO (Integrated Operation Automation and Control System) Overall System Presentation Speaker: Paulo Vieira 1

2 MRS Logística S.A. Profile Belo Horizonte Connects the 3 major cities in Brazil Rio de Janeiro São Paulo In the market since 1996; Heavy haul railroad mostly iron ore transportation; 1,674 km of track; 1.6 m gauge.

3 MRS Logística S.A. Profile MRS in numbers 150 MRS decided in 2004, among other actions, to replace its existing CTC Systems, that were based on old technologies from the 70 s

4 Project TimeLine 2003 Start up Preliminary Studies 2004 RFP Issued Basic Project Budget Analysis RFI RFP Original Proposals Reviewed Proposals Proposals Submission Analysis Q&A Negotiation Signature of Contract Project Development Tender Award 2007 Factory Tests Field Deployment Field Tests Project Development/Deployment 2008 Pilot Operation Project Deployment/Operation 2009 Project Deployment/Operation

5 Technical Perspective Conceptual Issues Signaling System Deciding on the usage of the existing Track Circuits Track Circuits are always a concern, however, provide: Train Vital Position Broken Rail Detection Train Integrity information To remove Track Circuits MRS would have to find a solution that could provide these functionalities Solutions offered to replace Track Circuits were not able to handle properly all the functionalities above MRS decided to keep the Track Circuits

6 Technical Perspective Conceptual Issues Signaling System Defining how to obtain a discrete train position MRS investigated some options: Balize systems + Tachometer Differential GPS Both are proven solutions MRS adopted a third option, using Track Circuit events The Issue T. Circuit Occupation Tachometer displacement Solution Adopted Vital Train positioning is defined by the Track Circuit occupation and Tachometer displacement However, tachometer positioning has an intrinsic error Track Circuit transition resets the Tachometer error Track Circuit position is fixed and known by the system

7 Overall System Architecture Integrated Operation, Automation and Control System A Full CBTC System ETCS Level 2 equivalent CCOI (Integrated Operational Control Center) SLS Center Servers (Safety Logic System) STT Center Servers (Train Land Communication System) CENTER CENTER MRS s Fiber Optics Backbone Data and Voice Communication Radio Base Station Object Controller FIELD FIELD Way Side Systems Hot Box Hot Wheel Derailment Detector Grade Crossing Onboard Control System Radio OBC ATC Event Recorder Existing Systems

8 System Architecture Components STT (Train Land Communication System) Uses a TETRA (Terrestrial Trunking Radio) Technology STT Center Servers (Train Land Communication System) STT Center Servers (Tetra DXT) Full Digital Data and Voice system; Interface to other technologies (VHF, PABX, and other); Not shared with other applications (dedicated to the CBTC system). DXT DXT Server Server Radio Base Station RBS (Tetra Base Stations TBS) Standard configuration of TBS has 2 carriers (4 channels per carrier); 1 Control channel + 7User Channels Total throughput is 28.8 kbps per carrier 800 MHz Frequency. TBS TBS Tower Tower Radio Onboard Radio Two digital radios per locomotive (Data and Voice); Different types of data being transferred: Signaling Vital Messages; Non vital Messages (like condition of the vicinity); Event Recorder Upload data (low priority). Tetra Tetra Radio Radio

9 System Architecture Components SSC (Signaling and Control System) Distributed Interlocking; Vital Protocol used in the Vital Messages (64 bits CRC). SLS SLS Servers Servers SLS Center Servers (Safety Logic System) SLS (Safety Logic System) Center Servers Three Processors in a 2out of 3 voting schema; Servers in Hot Standby special hardware (not COTS). Object Controller Object Controller Two processors in a 2out of 2 voting schema; Special Hardware (not COTS); Vital and non vital inputs and outputs; Cases with special design to support diverse condition (temperature, vandalism, heavy rain, etc). O.C. O.C. Deployment Deployment

10 System Architecture Components SCB (Onboard Control System) Radio OBC ATC Event Recorder ATC Automatic Train Control System Two processors in a 2out of 2 voting schema Calculates train brake curvature and enforces train stop Same basic hardware (processor) as the Object Controller Tachometers provide discrete train vital position Certification CENELEC (EN50155, , IEC61373) ATC ATC Hardware Hardware OBC OBC Hardware Hardware OBC Onboard Computer Non vital ruggedized computer; Provides the HMI where the driver interacts with the system Manages all the communication with the Center (appl. level) OBC OBC Screen Screen Event Recorder Captures information from locomotives in real time mode Downloads all data acquired while train moves Issues alarms and warnings at locomotive and at Center side Features for remote real time telemetry

11 System Architecture Components CCOI (Integrated Operational Control Center) CCOI (Integrated Operational Control Center) Integrated Operational Control Center Servers in dual hot standby configuration COTS hardware; Client HMI provides diverse functionalities to command and control train circulation; Integrates all the components of the SIACO system; Interfaces to other operational and corporate systems.
