TheX40 is a series ofelectric multiple units operated bySJ of Sweden. They are in service fromStockholm toLinköping,Västerås/Örebro,Uppsala andGävle/Sandviken, and since 2010 toGothenburg viaVästerås. Thedouble decker trains were built byAlstom from 2004–2008, with 43 units being delivered, either in a two-car or three-car configuration. It is based on theCoradia series, very similar to the FrenchSNCF Class Z 26500 double decker trains, and similar to theX60-series.
The X40 is the first truedouble-decker train to operate in Sweden, although the first and last cars of theY3 were built in a style similar todome cars, connected to single-deck coaches. From 2019 onwards, the bilevelStadler KISS (known as DOSTO in Sweden) has also been used in theMälardalen andUppsala regions of Sweden, and since 2023,Tåg i Bergslagen [sv] has operated the same train sets in theBergslagen region.
Among crew and technical support the vehicle early got nicknamed "Flodhäst", in English "Hippo - big, gray and unpredictable". The X40 is currently being refurbished which will modernise the double-deckers so that they can last for about 15 more years.
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 (125 mph). 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 isair conditioning, signal boosting for mobile telephones, electrical plugs at each chair, that is also equipped with radio.WLAN is available for free to all passengers.
There were many technical problems during the first year of operation in 2006, including problems with doors and the air conditioning. Complaints from passengers were that there was too little room for baggage and that the seat pitch was insufficient. These problems have been addressed through rebuilding the interior, which also included removing allvending machines andcoffeemakers from the trains themselves. 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 newSJ 3000 have replaced the X40 on the Stockholm-Sundsvall line.
X40 trainsets will be refurbished in 2024–2028 by FinnishVR FleetCare inOulu andPieksämäki. This refurbishment will modernise the double-deckers so that they can last for about 15 more years. The seats will be refurbished and get new fabric to make cleaning easier. The train sets will also get new lighting and an update of the passenger information system. The trains will be repainted. The 1st class compartment will be more comfortable but will retain its 2+2 seating, some of the four groups with tables will be removed to allow for more seats with sitting together and fewer with sitting opposite each other. It has not yet been decided whether coffee/vending machines will be reintroduced on the trains, something that was previously available on board.
The 27 X40 trainsets with three carriages (X40-3) will be refurbished between 2024 and 2028. SJ has an option to rebuild the 15 (or 16?) X40 trainsets with two carriages (X40-2).[1]
