  1. Advisor: Jörg Fenske, Dipl.-Ing. Slab Track System ÖBB–PORR Elastically Supported Track Base Plate Angela Kuo Porr Bau GmbH Railway Division www.porr-group.com

  2. Slab track development in Austria • Construction (space requirements,...) • Method (sensitivity of laying,...) • Quality (track set, acoustics,...) • Economy The ÖBB–PORR elastically suspended track support layer is now the STANDARD SYSTEM in Austria

  3. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate System Design Main element - track base plate - (TBP) 3

  4. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate System Design operating characteristics of elastic separation layer 4

  5. >430 System Design • High degree of prefabrication • Low construction dimensions Cross-section through pouring apertureQuerschnitt durch Vergussöffnung Cross-section beside pouring apertureQuerschnitt neben Vergussöffnung

  6. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate Construction Construction process 6

  7. Phase 1 Elastomeric layer Drainage formwork Endstops Reinforcement mat Earthing rod Construction

  8. Phase 2: Track base plates Rail installation Track positioning Construction

  9. Phase 3: Formwork Reinforcement cage Concreting with SCC Surveying of track Construction

  14. Noise absorbers fit for traffic Guard rails Emergency breaking system Track magnets Power rails Options Track equipment:

  15. Options Accessible noise dampers for emergency road vehicles

  16. till 1,80 m Options Large openings

  17. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate Repair and replacement Derailment repair 17

  18. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate Repair and replacement Replacement concept 18

  19. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate Adjustment of settlements (large) Adjustment using Track Base Plate 19

  20. Austria – Tauern Tunnel Ballast Track Slab Track Slab track projects • 10 km of slab track • In tunnel • Reduction of track gradient • Increased tunnel clearance • Construction during single-track operation

  21. On 25 bridges 5.6 km of slab track With mass-spring-system 4 Turnouts in slab track 6 bridge expansion joint construction 50 transitional construction Slab track projects Berlin Lehrte station East–West connection

  22. In tunnel 20 km of slab track 13 km of light, medium & heavy MS systems 49 turnouts in slab track Slab track projects Berlin Lehrte station north-south connection

  23. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate Slab track projects Vienna – St. Pölten High Speed Connection • 73 km of slab track • Mass-spring-systems • Earthwork • Bridges • Tunnels • In construction until 2012

  24. High Speed Line VDE 8.2 Erfurt – Leipzig / Halle 90km x 2 (180km slab track) ÖBB–PORR Slab Track System with Elastically Suspended Track Support Layer Slab track projects 67 % earthwork 60,5 (121 km) 16% on bridges 14,5 (29 km) 17% in tunnels 16,5 (31 km) (577 m) (1,012 m)   (248 m) (2,668 m) (297 m) (6,465 m / 2,112 m) (6.970 m) (6.466 m) (2.082 m) 24 VDE 8.2 Neubaustrecke Erfurt - Leipzig/Halle

  25. Tauern Tunnel Tauern Tunnel Arlberg Tunnel Slab Track Ballast Track Mass-Spring-Systems Emergency Vehicle Access ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate Berlin North-South Connection Over 270 km track reference Noise dampers

  26. ÖBB–PORR Slab Track System with Elastically Supported Track Base Plate Advantages of the system Low maintenance Settlement adjustments possible Structural-born noise and vibration control Repair and replacement plan High track precision Fast installation Large openings possible Even surfaced concrete quality Little reworking High added value • High degree of prefabrication • High early strength of SCC • Great driving comfort • Small construction dimensions 26
