Alstom Signs ~€460M Contract for Additional Driverless Metro Trains on Riyadh Lines 3, 4 and 6
The Metropolis trains will integrate with the existing Urbalis CBTC system and be maintained by Alstom, extending a fleet that already counts 116 delivered cars.
Alstom has signed a contract worth approximately €460 million (about US$585.5 million including VAT) with the Royal Commission for Riyadh City to supply additional driverless Metropolis metro trains for Riyadh Lines 3, 4 and 6 — the orange, yellow and purple lines. The trains will integrate with the existing Urbalis CBTC signalling system and be maintained by Alstom under the existing operations and maintenance contract.
The order extends a fleet that already includes 116 delivered trains and is booked in Alstom's Q2 FY 2026/27 results. The Yellow Line is expected to serve the World Expo 2030 site.
The deal continues the steady expansion of driverless, CBTC-based metro systems in emerging markets — following recent contracts and launches in Chennai and Sydney — underscoring how automation has become the default for new urban rail in regions investing heavily in transit.
