Qatar Rail on Wednesday announced the completion of tunnelling on the Green Line of the Doha Metro project with the breakthrough of a boring machine at Education City station.
Education City is the last underground station on the Green Line before moving towards the above ground station Al Riffa, the company said in a statement.
The announcement comes just days after Qatar Rail celebrated completion of tunnelling on the northern section of the Red Line.
Saad Al Muhannadi, Qatar Rail CEO, said: "Completion of tunnelling on the Green Line is yet another major milestone for the project and one we are delighted to have achieved ahead of schedule.
"Across the project as a whole, we are continuing to make significant progress and as we prepare to move from the construction to systems and architectural works, we are delighted to have been able to achieve all this within the timelines and budgets allocated for this monumental endeavour."
Tunneling on the Doha Metro Green Line began in September 2014 with six boring machines used to complete the 22km operational line which has 10 underground stations and one above ground.
Qatar Rail said the next construction milestone will be the completion of tunnelling on Doha Metro's Gold Line while later this year, the Red Line will also finish its tunnels.
Towards the end of this year, Qatar Rail expects to move from construction into systems installation as track, power supply and signaling starts to be installed.
The first phase of the Doha Metro project is expected to be completed in the fourth quarter of 2019, while completion of the Lusail Tram is set for 2020.
By 2030, all the three networks - Doha Metro, Lusail Tram and the long-distance rail, which will link Qatar with the GCC Rail network - are expected to be completed.
Qatar Rail said it expects to offer 600,000 passenger trips per day by 2021. By then, 37 metro stations are expected to be ready, with an average journey time of three minutes between stations.For all the latest construction news from the UAE and Gulf countries, follow us on Twitter and Linkedin, like us on Facebook and subscribe to our YouTube page, which is updated daily.
