The joint venture of Germany’s Deutsche Bahn and local real estate developer Qatari Diar has prequalified firms for the consultancy services contract for Doha metro project.

The metro project will run for about 300 kilometres across Doha city once it is complete. The network will consist of four lines, Red, Gold, Blue and Green.

The Red line is the first line to be developed and will run from the New Doha International airport (NDIA) to the West Bay area in central Doha.

The Gold line will run on an east-west route linking NDIA and the airport city with the industrial areas in the west of Doha. The Green line will run from the industrial areas in the south through central Doha and on to Education City. The Blue line will follow the coast road, running from NDIA to West Bay and on to The Pearl and Lusail.

The metro forms part of Qatar’s plan to spend $25bn on rail infrastructure in the lead up to the FIFA World Cup in 2022. Qatari Diar has invited companies to submit prequalification documents by 8 March for the project management consultancy contract for an automated people mover in West Bay.
