X3 (train)

X3 is an electric multiple unit train used by Arlanda Express on the airport rail link service between Stockholm Central Station and Stockholm-Arlanda Airport in Sweden. Alstom built seven of these four-train car units in Birmingham, which were delivered in 1998 and 1999. The X3 is part of the Coradia family, and can reach speeds up to 200 km/h.

The trains are painted grey with yellow ends with varying interior colors. The units use standard gauge tracks and are fed electricity at 15 kV  16.7 Hz AC like the rest of the Swedish railway network, but the trains use separate stations at Arlanda and dedicated tracks at Stockholm C; in both cases, the platforms are higher than at other stations in Sweden, allowing step-free access to the trains without the use of low floors.
