Here is the train that lays thousands of meters of rails a day between Gävle and Söderhamn

- The train comes from Austria and has been rented.

30 people work on the machine and 120 work before and after the train with track work, says Adam Larsson, project manager at the Swedish Transport Administration.

The old track is torn up and cut to five meters in length.

The train adds new sleepers, new tracks and new macadam, all at the same time.

The rails have been purchased from France.

Machine use in recent years

Laying railway rails and sleepers used to be a heavy job that was done by hand.

The entire Swedish railway network is laid by hand and is only in recent years that machines have started to do the job.

- This will be better and above all gentler for those who do the job.

This is also much faster than when rails were laid 120 years ago, says Adam Larsson, project manager at the Swedish Transport Administration.

The track change will cost SEK 400 million, which will last until the end of November.
