1. RAIL PROJECTS AND TRACK INSTALLATION SUPPORTED BY LONG-TERM TRACK MAINTENANCE SOLUTIONS

2. Today´s Challenges of the Rail Infrastructure Industry
Economic considerations drive railway industry in an increasing complex and competitive environment
Life Cycle Cost are predominant today
Upfront investments are weighted against maintenance cost
Clear cut requirements with regard to construction, operation and maintenance is required
Total Service Contractors offer total project management planning, construction and maintenance in certain instances even financing – (ppp-models)

3. Requirements to be met by the track (1)
Tracks have to be laid and maintained to provide a cost effective infrastructure
German Federal Railway defined in their Track Strategy project different levels of requirements:
Mandatory Requirements
Tolerated Requirements
Subsidiary Requirements

4. Requirements to be met by the track (2)
and summarized criterias:
Overall operational model
Availability
Economical
Riding Comfort
Construction and Maintenance Strategies Maintainability
Possible Alterations
Renewal Investments
Reliable supply of components
Risk/Failures
Safety
Damage Symptoms and restoration after derailment
Repair of possible fault symptoms in respective tracks
Other Requirements

5. Concept of Life Cycle Cost (LCC 1)
LCC Components and their interaction
Emergency Repairs
Maintenance
Investment
Inspection and Diagnosis

6. Concept of Life Cycle Cost (LCC 2)
The LCC Model – summarised in brief
Life cycle costs can only be optimised as a whole
Each cost component of LCC shall be analysed over an entire life cycle
Different track systems (e.g. ballasted track vs. ballastless track) can be compared by defining the individual value of the individual cost component according to the track system under review

7. Ballasted Track Line Wels – Linz / Austria

8. Track Construction and Maintenance (1)
Ballasted Track
Maintenance intervals – objective: achieve longest possible intervals

9. Tamping Intervals For Ballasted Tracks Depending On The Traffic Load

10. Track Construction and Maintenance (2)
Ballasted Track
Maintenance Intervals – objective: achieve longest possible intervals
Initial Track Quality – substructure
Permanent Way Ballast – quality of ballast
Maintenance of Rail Surface – grinding a key operation

11. Grinding Intervals For Ballasted Tracks Depending On The Traffic Load

12. Track Construction and Maintenance (3)
Ballasted Track
Maintenance Intervals – objective: achieve longest possible intervals
Initial Track Quality – substructure
Permanent Way Ballast – quality of ballast
Maintenance of Rail Surface – grinding a key operation
Infrastructure Elasticity

13. Ballastless Track – Loetschberg Tunnel / Switzerland

14. Track Construction and Maintenance (4)
Ballastless Track – an alternative to Ballasted Track
Why ballastless track?
A cost effecient solution at least in certain projects
Sleeper Pads
An additional low cost improvement

15. General Contractor in Rail Engineering
The benefits
All from one partner; use of synergies, reduced friction
No planning and functionallity risk – all is general contractor‘s responsibility
High level of schedule reliability
Easier Budget and Cost control
Complex logistical and construction site safety issues are centralized and in one hand

18. Details for Track Construction
Timing: Design: 10/2002 – 03/2004 Trials and Preparation: 01/03 – 09/04 Realisation: 04/2004 – 10/2006
Length of track: Total 57 km, 51 km in tunnel
Slab track system: LVT / Sonneville
Sleepers: 171‘000 blocks type LVT (60 cm spacing)
Rails: UIC 60: tons
High speed-turnouts: 2 on slab-track, 1 on ballasted track
Concrete: 80‘000 m³
Max. Operating speed: 250 km/h (in tunnel)
Totel value track construction: Euro 85 MIO

19. Requirements on Track Quality
Useful life for basic track layer, fill-in concrete (2nd pour) and sleepers at least 50 years
Resisting high impact and providing the possibility for simple maintenance
Keeping track tolerances of +/- 2 mm in horizontal und vertical direction
Keeping track gauge of 1435 mm -1/+ 3 mm
The requirements on the quality of the concrete surface regarding levelling and cleanliness are very high
Further impacts due to high utilization of the tunnel, maximum speed, axle loads, corrosion, etc.

20. Logistic Challenge Real logistic challenge in single-track tunnel
Just one single access route for transport and supply
Construction of various installations and temporary yards for efficient performance
Just-in-time co-ordination to guarantee material supply in all fields of activities
High speed of transport (about 60 km/h) requires special safety measures (control centre, identification of position)
Co-ordination and interface management with tunnel carcass construction, overhead line construction, mechanical equipment, cable laying and safety installations

21. Conclusions
Well defined and managed technical, functional and performance requirements in terms of construction, operation and maintenance underpin and are the essentials for the commercial success of a project and the subsequent cost-effective operation of a railway infrastructure
High quality execution of works and an optimised maintenance regime are still a must for a successful Life cycle project approach
For this reason the selection of the right partner – experience combined with enthusiasm for the project and commitment of executing staff
