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 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

Capacity constraints


The capacity situation in
the North is now stretched
to the max



Low punctuality and hard
to get more ore trains with
today's infrastructure

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!
