Rail infrastructure Asset Management regimesHow to secure high availability and optimal LCC

AvailabilityRisk based approach

LCC-optimal

Method Results

• Following risk of failure.

• Maintenance and large renewal

in same closure

• Work in night shifts – or short

closures.

• Full renewal of all railcomponents

• Use LCC-model to predict and

plan renewal 4 years ahead.

• Ten year renewal pause

• Bundle renewal activities across

assets

• Minor disturbance of traffic.

• Less volume in projects

• High unit costs

• Full line closure.

• Life prolonging activities.

• Maintenance on end-of-life lines.

• Renewal of individual railcomponents

– sleeper, rail or ballast. Or in

combination.

Model structure

• Asset data• Unit cost• Traffic hinderance cost• Model parameters

Technical engineering relationships:

• Deterioration of the assets described by Service Life relationship.• Maintenance activities described according to European models for tracks.

Financial optimization for each line section without constraints (only a 10 year renewal pause)

Financial optimization for each line section with constraints, e.g.:• Total renewal budget• Total activity budget

The methodology

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

In case of early renewal:• Penalty

Renewal of rail infrastructure on West Funen

West Funen

Daily train operation:

• 114 passenger trains

• 10 freight trains

20

West Funen Track and ground works

Replacement of 30 switches

Establishing 2 new switches, Middelfart

Elimination of 13 switches

Track renewal of 2.4 km track including new ballast bed

Upgrading of 4 buffer stops

Establishing one crossing on Odense Station

Establishing a dirt road on Odense Station

Establishing 17.3 km new ballast bed

Establishing new ballast bed under all replaced switches

Ballast sanitation of 53.4 km track

Drainage tasks

10.5 km drainage

5.3 km ditch

Catenary works

Establishing “protective earthing areas” on 17

bridges

Adjustment of power line on 75.5 km track

and 30 switches

Reconstruction related to the elimination of 13

switches

Replacement of “protective earthing” related

to track works

Replacement of protective covers related to

track works

Neighbouring projects

New walking tunnel in Middelfart

New insulation of two bridges

Platform works on Ejby, Tommerup, Gelsted

Signalling Programme (new cables)

Tasks related to interlocking systems and switch heaters

Benefits

Benefits and challenges

Challenges

• Cost savings

• Potential for bundling of projects

• Fewer passenger disturbances/fewer

announcements

• Operator: Possibility for major rolling stock

repair during the possession

• Entrepreneur: Effective use of resources

(men/machinery)

• Entrepreneur: Flexibility within work site area

• Neighbours: Only one long disturbance rather

than many nights/weekends

• Constraints on passenger and freight traffic

• High demand for coordination between asset

groups

• Operator: Some passengers are lost to the

alternative transportation form (car)

• Entrepreneur: Risk of resource

overload/capacity constraints
