Lines 4, 5 and 6 of the Riyadh Metro reach 24.5 million users

Lines 4, 5 and 6 of the Riyadh Metro have reached 24.5 million users since their inauguration. The project, designed and built by the FAST consortium, led by FCC, has been an engineering challenge. The Riyadh Metro, intended to transform urban life in the capital, will also improve the city's mobility ecosystem to address current demands and meet future needs, generating significant economic and sustainability benefits.
The Riyadh Metro, the largest construction project ever developed by a Spanish company worldwide, extends over 176 kilometres across a total of 6 lines, 85 stations and 7 workshops and depots, making it one of the largest urban transport infrastructure projects ever undertaken in the world.
Key project data
- For the construction of the green line (line 5), the FAST consortium used two tunnel boring machines (TBMs) with a diameter of 9.77 metres, which enabled the excavation of full-section tunnels, achieving world records for daily excavation progress.
- Of the three consortiums (FAST, BACS and ANM) that participated in the development of the Riyadh metro network, the FAST consortium, led by FCC, was the first to bring a 9.8-metre diameter tunnel boring machine to Riyadh. Two tunnel boring machines were used to drill 10.8 km of tunnels on the L5 line between San'ah and Zafrah, and the first one passed through Salah Al-din station on 4 October 2015, breaking world speed records.
- More than 12.2 kilometres of beams were installed in two sections in a record time of 1 year and 9 months, with an average construction and installation rate of 2.5 days/section.
