Integration of regional transport electric multiple units

The Fribourg Transport Authority and Stadler are collaborating to deploy a new fleet of multiple unit trains for regional transport infrastructure. The project addresses the modernization of public transit systems through the implementation of standardized, high-capacity railway technology.

Operational Challenges and Collaboration
The Fribourg Transport Authority requires modernized train sets to manage increasing passenger volumes and frequent stops inherent to regional transport operations. To manage this infrastructure upgrade, the operator commissioned Stadler to manufacture and supply thirteen standard-gauge multiple units. The collaboration leverages a previous tendering process negotiated by the Swiss Federal Railways in 2021, allowing the Fribourg Transport Authority to utilize established procurement parameters and technical specifications.

Technical Solution and Responsibilities
Stadler is responsible for the engineering and manufacturing of the electric multiple units, which are configured as four-car train sets measuring 73.5 meters in length. The technical architecture includes a maximum operational speed of 160 kilometers per hour, supported by high acceleration and braking parameters to optimize transit times between stations. The vehicle layout is designed for independent accessibility, featuring step-free entrances, continuous level transitions, and designated wheelchair spaces. The integrated passenger information systems and power infrastructure are standard across the units to maintain operational uniformity.

Deployment and Implementation
The implementation phase begins with the scheduled entry into commercial service of the first unit on the standard-gauge network in December 2028. Following the initial deployment, subsequent units will be integrated at a rate of one train approximately every two months. This phased rollout facilitates the gradual decommissioning of the legacy rail vehicles. Upon completion of the deployment cycle, the operational standard-gauge fleet will consist of twenty-one units, operating alongside an existing fleet of ten metre-gauge units on specific routes.

Applications and Use Cases
This railway technology is deployed specifically for regional transit networks characterized by short travel distances and frequent station stops. The system design facilitates efficient passenger boarding and alighting through wide doors, improving station dwell times. The trains offer a combined seating and standing capacity of 369 passengers per unit, including dedicated multi-purpose areas for bicycles and luggage, stabilizing transit operations during peak demand periods.

Results and Expected Impact
The capital investment for the infrastructure modernization totals 117 million Swiss francs. The integration of these multiple units is engineered to absorb increasing passenger traffic while maintaining schedule reliability. Serge Collaud, Director General of the Fribourg Transport Authority, stated: "equipped with state-of-the-art technology and offering high capacity, the FLIRT Evo trains will help us cope with the rising passenger numbers on our routes." Christian König, Deputy Sales Manager at Stadler, added: "The 13 four-car trains form the basis for even more attractive regional transport in the canton of Fribourg."
