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
Unconstrained LCC-optimality

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

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

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
