The X3 is a high-speed electric multiple unit train managed by Arlanda Express, serving the rail connection between Stockholm Central Station and Stockholm Arlanda Airport in Sweden. Built by Alstom at their Washwood Heath facility in England between 1998 and 1999, a total of seven four-car sets were assembled. This model is part of the Alstom Coradia series and can achieve speeds of up to 200 km/h.
Overview
These trains are characterized by a white body with yellow-painted ends and feature interiors designed in a Scandinavian style. They operate on standard gauge rails and are powered by the electrification system utilized across the Swedish rail network. At both Arlanda and Stockholm Central stations, specially designed platforms with increased height facilitate step-free boarding, improving accessibility for passengers.
In 2025, Arlanda Express plans to replace the X3 units with seven six-car Stadler Flirt trains as part of a planned modernization of their rolling stock.
