10 Rail infrastructure Asset Management regimes How to secure high availability and optimal LCC

Strategies Method Results

Availability • Following risk of failure. • Minor disturbance of traffic. Risk based approach • Maintenance and large renewal • Less volume in projects in same closure • High unit costs • Work in night shifts – or short closures. • Full renewal of all railcomponents

• Use LCC-model to predict and • Full line closure. LCC-optimal plan renewal 4 years ahead. • Life prolonging activities. • Ten year renewal pause • Maintenance on end-of-life lines. • Bundle renewal activities across • Renewal of individual railcomponents assets – sleeper, rail or ballast. Or in combination.

TAM 1.0

Ongoing development and updating of Asset Management System

13 Model structure

Technical engineering relationships: Financial optimization for each line section without constraints • Deterioration of the assets described by Service (only a 10 year renewal pause) Life relationship. • Maintenance activities described according to European models for tracks.

Sub models

Technical Unconstrained Constrained Inputdata optimality LCC-optimality LCC-optimality

• Asset data Financial optimization for each line • Unit cost section with constraints, e.g.: • Traffic hinderance cost • Total renewal budget • Model parameters • Total activity budget

14 The methodology

The Bath Tub model Postponed renewal Speed reduction Costs Costs Renewal costs Costs

Maintenance costs

Lifetime Lifetime Time of Optimal time of Optimal time of Optimal time of Postponed time investment/ investment/ renewal renewal of renewal reinvestment reinvestment

In case of postponed renewal: • Increased maintenance costs • Increased renewal costs • Risk of speed reductions (traffic hindrance costs)

In case of early renewal: • Penalty

17 Renewal plan

Major track possessions 2015-2018

18 Renewal of rail infrastructure on West Funen

Daily train operation:

• 114 passenger trains

• 10 freight trains West Funen

19 West Funen Track and ground works Replacement of 30 switches Establishing 2 new switches, Catenary works Elimination of 13 switches Establishing “protective earthing areas” on 17 Track renewal of 2.4 km track including new ballast bed bridges Upgrading of 4 buffer stops Adjustment of power line on 75.5 km track Establishing one crossing on Station and 30 switches Establishing a dirt road on Odense Station

Reconstruction related to the elimination of 13 Establishing 17.3 km new ballast bed switches Establishing new ballast bed under all replaced switches Ballast sanitation of 53.4 km track Replacement of “protective earthing” related to track works Neighbouring projects Replacement of protective covers related to New walking tunnel in Middelfart track works New insulation of two bridges Platform works on Ejby, , Drainage tasks Signalling Programme (new cables) 10.5 km drainage Tasks related to interlocking systems and switch heaters 5.3 km ditch New platform, Langeskov Station

24 Benefits and challenges

Benefits Challenges

• Cost savings • Constraints on passenger and freight traffic • Potential for bundling of projects • High demand for coordination between asset • Fewer passenger disturbances/fewer groups announcements • Operator: Some passengers are lost to the • Operator: Possibility for major rolling stock alternative transportation form (car) repair during the possession • Entrepreneur: Risk of resource • Entrepreneur: Effective use of resources overload/capacity constraints (men/machinery) • Entrepreneur: Flexibility within work site area • Neighbours: Only one long disturbance rather than many nights/weekends
