1 Capacity for Rail SP5 Migration to 2030/2050 Final.Conference.Madrid.September.2017 Burchard RIPKE and SP5 partners

2 Migration C4R solutions - selection Impact on infrastructure Investment Operation Slab Tack Rebuilding of track, sub-structure New S&C s Rebuilding of S&C s ++ 25t Axle Load Upgrade to E5, sub-structure, bridges +++ Longer Trains Sidings, axle counter, bridges, signalling ++ Increased Speed Maintenance of track, power supply Terminal Upgrades Rebuilding and upgrade of assets +++ New Monitoring System Sensors, data acquisition, evaluation Optimized freight wagons none 0 0 Most C4R solution will impact the infrastructure, related investment and operation Impact during migration 0 - small + - noticeable ++ - medium strong 2

3 Future boundaries and demands Demands on the future railway with respect to the track Demand Timeslots for maintenance - MTTR 100% 50% 50% Planned & unplanned unavailability - MDT 100% 50% < 1h/d Specific CO2 emissions (incl. embodied) 100% 80% 50% Resilience to severe weather conditions (measured by infrastructure down-time) 100% <75% <50% LCC (NPV) 100% 90% 80% Innovative track constructions are necessary to fulfil these demands 3 Where? Which construction? When? Migration?

4 Decision criteria for upgrading with slab track Capacity bottlenecks Availability of track < 85 % Alternative routes available Proofed slab track available Think about upgrading ballasted track with slab track! High maintenance cost for track Homogenous support conditions 4

5 Migration Impact on Freight Impact of track blocking on rail freight transport The track blocking in Rastatt demonstrates the sensitivity of rail system Blocking: 52 days Migration has to take into account the impact of blocking 5

6 Comparison of application of slab track and ballasted track C4R Aspect Type Compact Prefabricated Ballast standard Ballast optimized New construction Renewal o Earth structure Bridge Tunnel - single track double track Sensitivity for installation failures medium little very little very little Repair of rail support Degree of mechanizing medium good excellent excellent Type of slab track is important for rebuilding 6

7 Assumptions and Requirements Installation of slab track on an existing RCF Section length: 50 km double track Optimized installation procedure to minimize track blocking Use of existing ballast for HBL, drainage, Improvement of sub-structure is necessary on 30% of line New track construction SP1 solution No experience with slab track for freight or heavy haul lines Source: SP1 Cases Case 1 alternative routes are available Case 2 alternative routes are not available 7

8 Case 1 alternative routes are available Approval Approval for test Test installation Optimization Maintenance and disaster concept Planning & Preparation Installation Procedures Soil improvement Installation HBL Track S&C s Drainage Final Work 4 years (once) 2 years Appr. 125 days 10 days Blocking of track Estimated costs: 75 Mio / track Due to alternative routes track blocking is not a real issue 8

9 Case 2 alternative routes are not available Approval Approval for test Test installation Optimization Maintenance and disaster concept Planning & Preparation Installation Procedures Soil improvement Improvement of alternative routes Installation HBL Track S&C s Drainage Final Work 4 years (once) >> 1 year Appr. 125 days 10 days Blocking of track Estimated costs: >> 75 Mio / track Track blocking is a issue, alternative routes should be prepared 9

10 Case 2 alternative routes are not available Approval Approval for test Test installation Optimization Maintenance and disaster concept Planning & Preparation Installation Procedures Soil improvement Installation HBL Track S&C s Drainage Final Work 4 years (once) 1 year Up to 20x10 days 20x2 days Blocking of track Estimated costs: >> 150 Mio Track blocking is a issue, installation process is divided in 10 sections 10

11 Sequence for rebuilding ballasted track into slab track km Day m/d step task Rebuilding ballast/base layer Track removal + installation of plate Adjustment and grouting Completion and reworking 11

12 Necessary improvements for upgrading the track Automated installation procedures with high quality output Automated correction of track geometry like in ballasted tracks Proofed repair and renewal concepts Cost reduction 12

13 Migration of innovation Conclusions Net Industry Track Access Charge External costs road, rail, water Long-life cycle High investment in infrastructure Interoperability Infrastructure Rolling stock Railway System Signaling Operation To ensure European solutions, migration of innovations on RFC needs subsidy from EC! 14
