Trojena is making significant construction progress on site as it prepares to receive the first of two tunnel boring machines (TBM) in February, which will enable the construction of Trojena’s funicular railway. On its way from Germany, the 235-metre-long, 2,000-tonne TBM is one of two machines commissioned to bore a twin 3.8-kilometre-long time travel tunnel. The railway will run through the side of and up the mountain and will take guests from the Mirage Visitor Centre terminal to the Vault building. The TBM is designed and manufactured by German firm Herrenknecht. Philip Gullett, executive director and region head of Trojena, said: “This will be the first operating funicular rail system in the kingdom and the steepest TBM-driven funicular tunnel in the world. There is a one-kilometre height difference between the start of the tunnels at the bottom of the mountain to the breakthrough point at The Vault building, so this tunnel drive is not only complex but unique.” The machine has been procured as part of the Turkish-local joint venture Limak Holding and Al-Ayuni Investment & Contracting Company’s contract to undertake the tunnelling and excavation works for the project. n August last year,  Neom had awarded the joint venture an infrastructure development contract at Trojena. The scope covers the construction of the time travel tunnel, Mirage freight depot and Vault excavation works in the Gateway cluster of the Trojena development. The tunnel links the Mirage Visitor Centre and the Vault, Trojena’s centrepiece development. The Mirage freight depot will be located next to the Mirage visitor centre, providing access to the underground time travel tunnel. The Vault will be built vertically inside a hollow mountain that will fold in on itself. It will be 198 metres high, 253 metres wide and 864 metres long. The total surface area of the project is 200,000 square metres.   For registration as a supplier: https://www.neom.com/en-us/our-business/suppliers   (ICE RIYADH)
