en.Wedoany.com Reported - At an event held at Stadler's manufacturing facility in Valencia, Spain, the final exterior design of the EURO DuFour locomotive developed for SBB Cargo Switzerland was unveiled. This new electric freight vehicle marks a development milestone following the signing of the initial procurement contract.

As the launch customer for the EURO DuFour platform, SBB Cargo Switzerland has ordered 36 mainline locomotives, painted in the standard red livery of Swiss Federal Railways (SBB). Among these, 22 units will be equipped with onboard battery systems to support special operations. The procurement agreement also includes options for an additional 93 locomotives.

The EURO DuFour represents the manufacturer's strategic expansion of its European product portfolio. Iñigo Parra, Executive Vice President of Stadler's Spanish division, stated that this locomotive marks Stadler's strategic entry into the electric Bo'Bo' mainline locomotive segment, the most widely used category for freight transport in Europe.

In railway engineering, the Bo'Bo' wheel arrangement indicates that the locomotive is equipped with two independent bogies, each housing two independently driven traction motors. Compared to heavier six-axle (Co'Co') designs, this configuration achieves an optimal balance between tractive effort and wheel-rail adhesion, while reducing rail wear on sharp curves. The battery equipment integrated into the 22 designated locomotives provides last-mile capability, allowing mainline electric locomotives to operate on non-electrified track sections without the need for additional diesel shunters for the final leg of freight transport.
