Dedicated Line: MRS Logística Brazil MRS s CBTC Project SIACO (Integrated Operation Automation and Control System) Overall System Presentation Speaker: Paulo Vieira 1
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.
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
Project TimeLine 2003 Start up Preliminary Studies 2004 RFP Issued 2005 2006 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
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
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
