what is it?
The X40 is a series of electric multiple units operated by SJ, the primary passenger train operator in Sweden. They are in service from Stockholm to Linköping, Västerås/Örebro, Uppsala and Gävle/Sandviken, and since 2010 to Gothenburg via Västerås. The double decker trains were built by Alstom from 2004 to 2008, with 43 units being delivered, either in a two-car or three-car configuration.

fun facts
- First built 20 years ago, in 2006.
- Top speed is 1.5× a car on the Dutch motorway (130 km/h).
- At full speed it would cover Amsterdam–Utrecht (≈ 40 km) in 12 minutes.
- 2.4 MW is about 28 family cars (~85 kW each) flat out.
- Weighs about as much as 23 African elephants (~6 t each).
- 55.1 m long: about 12 cars parked nose to tail.
- Seats 153: 3 full city buses (~50 seats each).
- Still in service after 20 years.
multiple unit: A self-propelled train: motors are spread under the passenger cars, so no separate locomotive.
