5 Appendix A Concerning tunnels and stations for the 5 th and 6 th RAILWAY TRACK AT AYALON CORRIDOR Preliminary Design - Tel Aviv Metropolitan Section General Israel Railways Ltd. ("ISR") is performing now the Preliminary Design of tracks 5 and 6 at the Ayalon Corridor. The project starts at Shefaim, north of the Tel Aviv area, continues through the Tel Aviv Metropolitan area including three (3) stations and finishes at the Ben Gurion airport, South East of Tel Aviv with a total length of approximately 27 km. Fig. 1 Horizontal alignment on aerial photo The design team already submitted an initial design and report. A vertical alignment is proposed at the Tel Aviv area at about 50 to 60 meters under the soil surface and about 40 to 50 meter under the water table. Soil in the Tel Aviv area includes mainly sand and sand stones (Kurkar). Sand stone ranges from rather soft (K1) to hard (K4) rock. Some layer of clay and sand clay may also be present. From the hydrological point of view, the area is part of the Mediterranean coastal area aquifer. At the Tel Aviv section there are three stations, from North to South as follows: Savidor Station close to the existing station at surface, to Ayalon Highways, Arlozorov St. and Namir road. Hashalom Station - close to the existing station at surface, to Ayalon Highways, Hashalom St., Menachem Begin St. and the Azrieli Towers. 5

6 Hagana Station - close to the existing station at surface, to Ayalon Highways, Hagana St. and Menachem Begin St. A launching shaft for TBM construction will be placed south of Hagana Station at Mikve Israel and a receiving shaft will be placed close to Savidor Station. The distance between these two piers is about seven (7) kilometers. The stations are located at very populated areas. Placing of access piers for stations is strongly limited by existing roads, buildings, infrastructures, etc. Fig. 2 Stations location at Tel Aviv Metropolitan section. Operational Scheme in the area of stations General Requirements 1. Tunnel widening must continue beyond platform station site to allow train crossing. 2. Minimum platform width, including central staircases, should be 12 meter. 3. A properly connection between the tunnels and the platform is required. 4. The platforms are 400-meter-long and the distance between the turnouts is approximately 1000 meter. So the length of tunnel widening will be also approximately 1000 meter for each station. 6

7 Alternatives for Construction The initial design at Tel Aviv section proposed two alternatives: Alternative 1: two TBM tunnels of approximately seventeen-meter external diameter each with three-meter local tunnel widening at platform station sites (figures 3a, 3b). Alternative 2: four TBM tunnels of ten-meter diameter each (figure 4). Alternative 1 Fig. 3a Station cross section with two TBM tunnels and side access shaft. 7

8 Fig. 3b Station cross section with two TBM tunnels and central access shaft (Note: Side platforms with 2 central tracks, for each pair of tracks is also a possible solution) At Alternative I, tunnel widening must continue beyond platform station site to allow train crossing. Minimum platform width, including central staircases, should be 12 meter. A properly connection between the tunnels and the platform is required. The platforms are 400-meter-long and the distance between the turnouts is approximately 1000 meter. So the length of tunnel widening will be also approximately 100 meter for each station. 8

9 Alternative 2 Fig. 4 Station cross section with four TBM tunnels. (Note: the shaft maybe located either at side of tunnels or centered between the tunnels) Scope of Services The solution shall include general concept of design and tunneling construction methods for the stations and the required switches between them (Note: cut & cover method is not allowed). It shall also include general ideas and technologies for connections between tunnels, central platform, shafts and staircases. 9
