3 India’s Rail Network Second largest railway in the world under a single managementSecond largest railway in the world under a single management OwnsOwns –63,100 km of track –6,900 stations –7,800 locomotives –4,700 EMU/DMU cars EmploysEmploys –1.5 million permanent employees –Almost as many part-time employees OperatesOperates –14,400 trains daily (8,900 are passenger) CarriesCarries –14 million passengers daily –1.5 million tonnes of freight daily

4 Safety Challenges Faced IR’s Corporate Safety Plan goals are to:IR’s Corporate Safety Plan goals are to: –“Make railways more reliable and a safer mode for transportation of men and material” –“Stimulate the implementation of modern, proactive and systematic safety measures” –“Bring about both qualitative and quantitative improvements in safety performance” –“Encourage safety research and development” –“Reduce consequential train accidents”

5 Modernisation Challenges Faced IR’s Integrated Railway Modernisation Plan goals are to:IR’s Integrated Railway Modernisation Plan goals are to: –“Ensure the railways not only sustain the current level of performance but are also able to cater to the growing demands of passenger and freight traffic” –“Provide modern and efficient services to millions of its customers” –“Become a World Class railway system in the foreseeable future”

6 Why Specifiy ERTMS/ETCS? Assists Indian Railways to meet their safety and modernisation goals byAssists Indian Railways to meet their safety and modernisation goals by –Providing a widely accepted standard –Accommodating multiple vendors –Providing a robust platform for technology transfer and local manufacture –Permitting customisation to meet Indian Railway’s needs –Eliminating human error leading to : Signals passed at dangerSignals passed at danger OverspeedingOverspeeding –Accommodating interoperability

7 TPWS TPWS = Train Protection and Warning SystemTPWS = Train Protection and Warning System Colloquialism used by Indian RailwaysColloquialism used by Indian Railways It applies to the ETCS Level 1 concepts and the UIC/UNISIG specificationsIt applies to the ETCS Level 1 concepts and the UIC/UNISIG specifications It does not, in Indian terms, apply to the UK implementation that is based on different technologyIt does not, in Indian terms, apply to the UK implementation that is based on different technology

8 Introduction of TPWS In early 2004 Indian Railways called tenders for two Train Protection and Warning System pilot projectsIn early 2004 Indian Railways called tenders for two Train Protection and Warning System pilot projects These projects were specified to conform to ETCS Level 1 and be upwardly scalable to meet the full supervision mode of ETCS Level 2These projects were specified to conform to ETCS Level 1 and be upwardly scalable to meet the full supervision mode of ETCS Level 2 Late in 2004 Ansaldo Signal was awarded both projectsLate in 2004 Ansaldo Signal was awarded both projects Ansaldo Signal subsidiary, Union Switch & Signal India will deliver both projectsAnsaldo Signal subsidiary, Union Switch & Signal India will deliver both projects The two projects include manufacture, supply, design, test and commission of the on-board and trackside equipmentThe two projects include manufacture, supply, design, test and commission of the on-board and trackside equipment

9 General Requirements Trackside EquipmentTrackside Equipment –Balises –LEUs On-board EquipmentOn-board Equipment –On board processor –Drivers control and indication panel –Balise antenna and BTM –Impulse generator – tacho –Brake interface –Service and emergency brake valves –Isolation unit

10 Functional Requirements Balise identification and data acquisitionBalise identification and data acquisition Calculation ofCalculation of –Speed profile –Permitted speed –Release speed Speed monitoringSpeed monitoring Unplanned passing of signal at stop - train tripUnplanned passing of signal at stop - train trip Planned passing of signal at stop – bypass controlPlanned passing of signal at stop – bypass control Audio Visual WarningsAudio Visual Warnings System health indicationSystem health indication Data loggingData logging System isolationSystem isolation
