The work includes the completion of engineering design services, mainly

work drawings and the execution of railway engineering work for the Østfold railway and

the Follo railway from the two altered tunnels at Oslo S, through a new tunnel in Klypen

towards the portal in Ekebergåsen. The track for the incoming Østfold railway continues

through the tunnel constructed by EPC D&B until the South Portal at

the Bekkelag tunnel. The outgoing Østfold railway track comes from the tunnel in Klypen

and will be joined to the existing tract at Loenga. The work also comprises the connection of all

railway engineering disciplines, including external signals with the existing track at Loenga,

Oslo S and new tracks in the portal in Ekebergåsen.
