Qatar has invited bids for its planned express airport rail line, the first of five planned rail projects the country will undertake over the next ten years.
Work involves building a railway station terminal for the express line, which will connect the airport with rail and metro stations in downtown Doha as well as with other rail networks.
The project, called the Passenger Rail Station Box, will be overseen by UK firm Mace International and is expected to be complete in 2011.
The overall project to construct five new rail lines is part of the country's plans to build a national railway system in another ten years.
The lines include an east coast rail link between Ras Laffan and Mesaieed, a high-speed link from Doha to Bahrain across the Qatar Bahrain Causeway, a freight link connected to the planned GCC rail network, a Doha metro network and a light rail network serving residential developments.
Qatari Diar Real Estate Investment Company and German firm Deutsche Bahn have already developed a conceptual design to bid for the project.
