Traffic management system, Tallinn area (Tallinn-Keila-Paldiski, Keila-Riisipere) 11.01.2017
Overview Status quo (current situation) Project scope geographical & technical General requirements Implementation limitations Overview of the track works Timeline
Traffic management system - status quo Built mainly in 1960 s (the first stations even in 1957) lack of reliability One station (Paldiski) still manually operated CTC not originally designed and used Station layouts not corresponding to actual and future needs Several bottlenecks between Tallinn-Keila-Paldiski: - Tallinn station capacity exceeded - Keila-Pääsküla section second track missing - Keila station hub station has only waiting platform between tracks - Paldiski station only one track for incoming/outgoing passanger trains
Kopli Railway signalling and control systems (CURRENT): One train on track simultaneously Semi automatic line block system 3x automatic line block system 4x automatic line block system 3xAB (not included in the project scope but interface needed) Semi automatic LBS (not included in the project scope but interface needed) Semi-automatic line block system
Geographical scope Configuration Tallinn Balti Pääsküla B/P89 Valingu B/P Keila Vasalemma Riisipere Klooga Kloogaranna Paldiski
Technical scope (1) Stage 1: 8 stations (updated layouts) with electronic interlocking Automatic train protection (automatic line block system with 4 signal aspects) between Tallinn-Keila Combined line block system (with axle counters and coded track circuits) between Keila-Paldiski and Keila-Riisipere Section between Klooga and Kloogaranna will be controlled by logical occupancy scenario Different subsystems level crossings (17), coded track circuits, point heatings Interfaces with soviet designed subsystems (3) semi- and autoblock line systems LED signal modules (maintenance free; day/night dimmable) Containers and modular buildings Second track between Keila-Pääsküla (max preparation needed in Stage 1)
Technical scope (2) Stage 2: Second track (signalling part) between Keila-Pääsküla ( not in the same tender ) Additionally (excluded from interlocking tender): FOC installation (approximately 90 ) + core network equiptment (all IP) New power supply (feeding) lines Timetable simulator (normatiive timetables)
Technical scope (3) Coded track circuits considered as a part of Interlocking, but no SIL4 requirement Level crossings (17) will be excluded from the scope EVR drives and manages LX engineering and compilation (plug and play equiptment ready for contractor. Process description in tender) LX installation and field works included in scope. LX interface description added to tender. Integration with interlocking required. Interfaces with existing (connected) or other traffic management systems outside EVR infrastucture Automatic Traffic Management System (automatic route setting) CTC Safety compliance and Security, standards and requirements Operations and Support after commissioning?

Automated traffic planning process
TRACKWORKS - Renewing sections marked with light blue 42 of track renewal 46 pcs mainline turnouts excange
Overall scope (trackworks) Track capital renowation (removal of old rails, sleepers and ballast and new track laying) Mainline turnouts excange Pedastrian- and level crossings renowation Modernization of railway station layouts (cooperation with Traffic management project)
Limitations during implementation Passenger operation ongoing during installation Limited testing time during non-operational-times (at night) Commissioning in phases with minimal disturbance of the normal traffic Ongoing track renewal works (probably the schedule will be fixed before the signalling tender) Possible changes in station layouts (signalling installation preparations should be divided between different stages)?
