Need for increased capacity
Swedens 10 year strategic national transport plan
– Parliament and Government;
All transport modes calls for 417 billion SEK
The state budget framework embracing all means
of transportations

Operation and maintenance of roads

Operation and maintenance of the national
railway network

Investments for constructing roads, railways, locks
(maritime) and navigable waterways:
217
An additional 65 billion SEK in cofinancing and 15.6 billion SEK
in track access fees (railway)
1 USD$ = 0.8 Euro = 7 SEK

Expansion plans for LKAB
2013 - 2020
• Increase haulage from 27 Mton to 50 Mton
• Increase no. of train pairs from 14 to 23 per day
• Increase axle load from 30 to 32,5 ton
• Reduce cycle time
Efficient Train Operation
On Line Driver Assistance System in operation since summer of 2012
Energy saving trend
Maintenance – some challenges
•
•
•
•
•
•
•
•
•
•
More traffic – need for more track possession time
for maintenance – gives less capacity!
More maintenance outside the summer period.
Technical solutions that minimalize maintenance.
Technical solutions that is easy to maintain.
Keep the track forces as low as possible.
Are the superstructure, 54 kg rail and wooden
sleepers, strong enough?
Friction management in cold climate?
Controlling the wheel/rail interface.
New double track - 40 tons axel load & 16 ton/m?
Research and development will be important!
