Editing X 2000 (section)

==Technical==
The X2 was designed for old main lines with tight curves and with continuously welded rails (the train has a maximum axle load of {{convert|17|t|1}}, which causes large forces on the track). However, since 1990 a lot of new high speed lines have been constructed in Sweden, both upgraded lines and new lines. These upgraded or new lines always have ATC, continuously welded rails on concrete sleepers and no crossings with road and rail at the same level. The tilting function is not used on these lines.

The max power continuous output of the power car is {{convert|3260|kW|hp|abbr=on}}, which is comparatively low for a fast train. It also enabled SJ to say that it does not consume more power at {{convert|200|km/h|abbr=on|round=5}} than older Rc-locomotive hauled trains at {{convert|130|km/h|abbr=on|round=10}}.

The X2 trains have mostly run at the X&nbsp;2000 service level, but have periodically been used for [[Linx (railway company)|Linx]] traffic (2000–2004) as well as regional services, for which fewer coaches were used to improve acceleration. All X2 trains are maintained at [[Hagalund]] depot in Stockholm and Olskroken depot located just before [[Gothenburg Central Station]].

Each train also has a UB2X coach with a driver's place, and a URB2 coach with a simple restaurant.

In the beginning there were many more UA2 first class coaches than UB2 second class coaches. But after a decision that state employees should normally use second class for train journeys in their works instead of first class, something many companies followed, many UA2 have been rebuilt into UB2.
