X40 is a series of electric multiple units operated by SJ of Sweden. They are in service from Stockholm to Linköping, Eskilstuna/Arboga, Västerås/Örebro and Gävle/Sandviken, and since 2010 to Gothenburg. The double decker trains are built by Alstom since 2004, with 43 units being delivered, either in a two-car or three-car configuration. It is based on the Coradia series, very similar to the French SNCF Class Z 26500 double decker trains, and similar to the X60-series.
The double deckers have a little higher passenger capacity than conventional cars, with 85 compared to 78 seats. Wider doors allow the trains to make only 30 second stops in smaller stations and 60 second stops in larger stations. Top speed is 200 km/h. Often the trains are paired, with one two-car and one three-car unit. The X40 has both first and second class, but with the same level of comfort. There is air conditioning, signal boosting for mobile telephones, electrical plugs at each chair, that is also equipped with radio. WLAN is available for a surcharge.
There were many technical problems during the first year of operation in 2006, including problems with doors and the air conditioning. Complaints from passengers included that there was too little room for baggage and that the seat pitch was insufficient. These problems have been addressed through rebuilding the interior. The trains are specified for regional commuter traffic, and some complaints come from passengers on longer journeys. For example, a common route for the train is Gävle-Stockholm-Linköping, with stop at Arlanda Airport, which means that tourists with heavy luggage use the train. During 2011 they have been used for even longer distances, like Stockholm-Örebro-Göteborg and Stockholm-Sundsvall, which has added to these complaints. In 2012 the new SJ 3000 will replace X40 on some of these longer trips.
