ArRiyadh Development Authority (ADA) has completed the end of Tunnel Excavation works for Line 5 (Green Line), one of the three lines being constructed by FAST Consortium (Freyssinet Saudi Arabia, Alstom, Samsung, Strukton, Setec and Typsa) – one of the three international Consortia commissioned to build the six-line Riyadh metro project. The announcement took place on June 8, 2016 during a ceremony in the presence of the Governor of Riyadh, His Royal Highness Prince Faisal bin Bandar bin Abdulaziz Al Saud, Transport Minister His Excellency Suleiman Al Hamdan, in addition to other dignitaries from different Government Ministries and VIP Guests.
FAST Consortium is commissioned to build the Yellow, Green and Purple lines – 33 km of viaducts, 22 km of underground and 9 km of at-grade. The Green Line runs underground within a bored tunnel along King Abdulaziz Road, one of the main arteries running through the city of Riyadh. The length of the line is 13 km and it features 11 deep underground stations, in addition to two transfer stations with the Red and Blue lines.
The Riyadh Metro project has seven tunnel boring machines (TBMs) working on the tunneling under the city. The Green Line project marked the second TBM to complete excavation works in the city.
In addition to announcing the end of tunnel excavation work, a full-size mock-up of the Riyadh Metropolis train manufactured by Alstom was unveiled. The event also marks the kick-off of the construction by Alstom of the track works, an important milestone for the project. The works will commence within an at-grade section of the Yellow Line, and will be the first tracks to be installed throughout the Riyadh Metro project.
In 2013, Alstom and its consortium FAST were awarded a contract to supply three metro lines totalling a length of approximately 64 km. Alstom is supplying a fully integrated metro system which includes: 69 Metropolis Trains, Urbalis signaling, the energy recovery system Hesop as well as tracks.
The Metropolis trains for the Riyadh Metro Project are composed of two cars per set and are each 36 m long. Each train features three classes: first, family and single class. The trains are driverless and 100% motorized, allowing them to run on gradients of up to a 6% slope.
The trains will offer passengers a high level of comfort, ergonomic seating, LED lightning, air conditioning and advanced passenger information systems.
In addition to the Metropolis trains, Alstom will provide Urbalis, its CBTC (Communication Based Train Control) signaling solution, as well as the power supply and Alstom’s energy recovery system Hesop. All subsystems have been optimized together to reduce energy consumption.
