Passenger services in the United Arab Emirates have begun carrying riders aboard diesel trainsets supplied by Spain's CAF and China's CRRC, marking the first revenue operation for the two fleets in the country.

The entry into service confirms delivery milestones set under the UAE's passenger rail programme, which has contracted rolling stock from both European and Chinese manufacturers. CAF and CRRC each supplied diesel units for the network, and both types have now cleared the commissioning phase to carry fare-paying passengers.

What does the opening change for the network?

The shift from testing to passenger operation converts dormant fleet capacity into usable service. Until now, the diesel trainsets delivered by the two suppliers had been undergoing trials and certification rather than running to a public timetable.

With the fleets now in service, the operator can deploy the units across routes where electrification is absent, extending scheduled passenger coverage beyond what existing rolling stock alone could support.

Who are the suppliers involved?

CAF, headquartered in Beasain, Spain, is one of Europe's established multiple-unit builders, with diesel and electric trainsets in operation across European and export networks. CRRC, the state-owned Chinese rail manufacturing group, is the world's largest rolling stock producer by volume and has supplied diesel units to a growing list of Gulf and international customers.

The UAE order placed both suppliers on the same national network — an arrangement that gives the operator dual sourcing for diesel traction and a basis for comparing fleet performance in identical operating conditions.

What happens next?

The passenger launch reported by trade publication Rollingstock positions the trainsets for expanded timetabled operation as the UAE continues to build out its rail offering, with fleet deployment and service frequency now the metrics to watch.
