SAUDI ARABIA:

Alstom unveiled a Metropolis trainset for the Riyadh metro at its Katowice factory in Poland on February 7.

The Metropolis trainset destined for Line 6 is the fifth that Alstom has produced for Riyadh; the first left the factory on January 10. Deliveries are due to be completed in 2018.

Alstom is supplying 69 two-car driverless trainsets for lines 4, 5 and 6 as part of the FAST consortium that also includes FCC, Samsung C&T, Freyssinet Saudi Arabia, Strukton, Setec and Typsa. Alstom’s €1·2bn share of the €6bn turnkey contract also includes the supply of Urbalis CBTC signalling, power supplies and its HESOP energy recovery system.

The trains are 36 m long and 2 710 mm wide. The external and internal livery will match the colours of the lines: yellow for Line 4, green for Line 5 and purple for Line 6. This is intended to make the metro easier to use for residents who are not used to this mode of transport.

There are three classes of accommodation. First class features transverse seating; family class has transverse, longitudinal and tip-up seats; single class has longitudinal and tip-up seats. All three classes have wheelchair spaces. Trains for lines 5 and 6 have capacity for 231 passengers including 69 seated, whereas those for Line 4, which will serve King Khaled International Airport, have capacity for 228 passengers including 57 seated. The seat moquette design is inspired by traditional Arabian architecture and the handrails are shaped like palm trees.

Adaptations for the local desert climate include air-conditioning and door seals to prevent sand ingress. All axles are powered, giving a maximum speed of 90 km/h and ability to climb gradients of up to 6%. They will draw power at 750 V DC from a third rail. Lines 4 and 6 will share a depot.

Several Alstom sites in France are involved in the manufacture of the trainsets. Bogies are coming from Le Creusot, control systems from Villeurbanne, traction motors from Ornans and onboard signalling equipment from Saint-Ouen.

Traction subsystems and auxiliary converters are being supplied from Charleroi in Belgium, with passenger information and security systems from Madrid in Spain. The aluminium car bodies are being made in Katowice, where final assembly is taking place. More info
