1 The Follo Line Double track Oslo - Ski Janette Brask Project Manager Stefan Kunz Assistant Project Manager

2 The Follo Line 22 km new double-track railway line between Oslo S and Ski No stations between Oslo S and Ski Designed for at least 200 km/h or higher Preliminary budget of EUR 1,53 billions (will be adjusted)

3 The Follo Line: background The Follo Line will meet the increased demand for rail capacity south of Oslo: 1,1 million inhabitants in the region passengers every day 30 % population increase by 2025 Road traffic is increasing Currently no spare capacity on neither rail nor road.

4 The Follo Line: the gate to Europe Use of The Follo Line as the innermost part of a possible new high-speed line to Sweden. May give the decision of the speedstandard for the Follo Line

5 The Follo Line: facts The existing Østfold line has 12 local stations The Follo line will function in combination with Østfold line Distribute the trains across the two lines Maximum use of rail capacity for train movements

6 The Follo Line: five sections Connection to Oslo Central station The tunnel The open section north of Ski station Ski station Ås passing track

7 The Follo Line: schedule Main planning Impact assessment for public scrutiny Area development plan for public scrutiny Detail planning Permission from the Ministry of Transportation and Communications to start the constructions work Ski station: The first construction phase starts in The Follo line: Most of the contracts will probably be agreed between 2013 and 2016

8 Design contracts Connection Oslo S Tunnel Open section Ski station Ås passing track Aas-Jakobsen AS Rambøll Signalling (design) COWI AS JBV internal Atkins Railway Technology (design) Aas-Jakobsen AS Norconsult AS Multiconsult AS Civil works (planning)

9 Civil work contracts Connection Oslo S Tunnel Open section Ski station Ås passing track Jernbaneverket is currently working in a new contract strategy for the construction phase. We will bring you more information by spring Dead line for prequalification 19th December 2011 (parking tracks) Dead line for prequalification 23rd November 2011 (parking tracks) Signalling Railway Technology Civil works

10 Connection to Oslo central station

11 Connection to Oslo S A challenging task: - Civil works while rail traffic operating - Relocate existing Østfold line - Cultural heritage

12 Connection to Oslo S Cultural Heritage Map Connection premises Potential of finding ancient monuments Avoiding the most vulnerable places with our current track arrangement. Secure Likely Medieval cultural heritage Medieval cultural heritage Unsecure Medieval cultural heritage Possible Other cultural heritage Oslo

13 Connection to Oslo S

14 Connection to Oslo S Existing Østfold line Klypen Oslo

15 Connection to Oslo S Cut and cover - concrete ceiling above the tracks gives a continuous landscape. Civil works will not be affected by traffic in operation

16 The open section north of Ski station

17 Connection to Ski station Two new freight tracks Relocate Østfold line The open section Langhus-Ski

18 The open section Langhus-Ski Follo line Østfold line Freight track West Freight track East

19 The open section Langhus-Ski Noise barrier and maintenance road Existing Tracks New Tracks

20 The open section Langhus-Ski Ground conditions (wet clay) Construction near existing tracks with train traffic Transport of masses from neighbour sections Construction phases and interface railway installations (critical path vs. Ski station)

21 Ski station

22 Ski station Ski station has 3 constructions phases 1. Relocating existing cables 2. Construction of new train parking 3. Main works

23 Ski station Eastern line Western line

24 Ski station Main works Train parking area Ski station has 3 constructions phases 1. Relocating existing cables 2. Construction of new train parking 3. Main works

25 Ski station 6 tracks to three platforms Improved connections between trains, buses, taxis and cars Improved facilities for disable persons An important contribution to a more integrated public center of Ski town Increased train capacity Reduced barrier East - West

26 Renewed Ski station Bus terminal Eastern line Train parking tracks T. B east T.B west Pedestrain underpass New road overpass New footbridge with stairs and ramp to platform New pedestrian underpass Stairs, ramps and elevators to the platforms Parking area for cars and bikes Western line 4 train parking tracks with 2 service platforms with a capacity of 12 commuter trains Base for daily cleaning and parking for trains 2 technical buildings (T.B) New bus terminal 26

27 Ski station: challenges Construction works next to existing railway The soil conditions are poor Public activity with people, cars and buses Goal: affect regular railway traffic as less as possible

28 The passing track at Ås

29 Ås passing track Two passing tracks for freight trains

30 Ås passing track Rebuilding of Ski station requires an alternative solution for: Passing of freight trains when track 4 at Ski station is temporary removed Managing freight trains traffic in order to maintain rigid timetables for passenger traffic.

31 Ås passing track - 2 passing tracks with effective length of minimum 750m - Double switch in the north (towards Ski) - New or relocation of existing double switch in the south (towards Ås)
