AtkinsRéalis and Siemens Mobility Secure Major Rail Systems Contract for Québec City's TramCité Project

AtkinsRéalis and Siemens Mobility have won a co-development contract to deliver the rail systems component for TramCité, a major new transit project in Québec City, according to Financial Post. The deal covers the integration of rail systems and technologies, oversight of testing and commissioning, and long-term maintenance of the network.
The contract follows a Progressive Design Build model. This approach lets teams refine the technical plan, schedule, and final pricing before full execution begins, according to Calgary Herald.
TramCité is one of Québec City's most significant public transit investments in decades. The project aims to build a modern tram network that connects key parts of the city. AtkinsRéalis and Siemens Mobility will jointly handle the systems side — the technology and infrastructure that makes a tram network actually run, according to Montreal Gazette.
Their scope includes integrating all rail systems, overseeing testing, commissioning the full network, and providing maintenance over the long term. This end-to-end role means the two firms will be involved from build-out through daily operations.
The contract uses a Progressive Design Build structure. Under this model, the contractor refines the design, schedule, and price before committing to full delivery. It reduces risk for both the public client and the contractor, according to Fort McMurray Today.
Clear performance and delivery targets are set before the project moves into full execution. This gives the Québec City transit authority greater confidence in cost and timeline outcomes before major spending begins.
AtkinsRéalis President and CEO Ian L. Edwards highlighted why this win matters. He said integrated systems expertise is critical to delivering complex transit infrastructure. In plain terms, a tram network is only as good as the technology tying it all together — signals, power, controls, and communications.
AtkinsRéalis trades on the Toronto Stock Exchange under the ticker ATRL. The company describes itself as a world-class engineering services and nuclear firm, according to Financial Post. Pairing with Siemens Mobility — a global rail technology leader — strengthens the bid's technical credibility.
Siemens Mobility is one of the world's largest rail technology suppliers. The company provides tram vehicles, signalling systems, and digital rail solutions across dozens of cities globally. Its role in TramCité will likely center on supplying and integrating core rail technology, according to Sault Star.
Together, the two firms cover both engineering services and rail technology — a combination well suited to a project that demands seamless coordination between design, systems, and operations. The co-development phase will now begin to lock in the final technical and commercial details before full construction gets underway.
