Traduction automatique. Texte original en: EN - afficher l'original The X2 trains, which handle a large part of SJ's long-distance traffic, are used heavily, and when trains need to be taken out of service, this means disruption. In order to relieve the high-speed trains, SJ decided in 2001 to rebuild passenger cars and Rc locomotives as reserve trains for X2 units. A total of 27 eighties carriages were rebuilt so that you got four sets of trains. The wagons received the letters A11, B11 and RB11. The wagons received a new color scheme in dark blue and an interior with the same comfort as the X2. The trains have (unofficially) gone by the names "X2000R", "Blue X" and "IC11" and are allowed to go up to 160 km/h, i.e. slower than X2 units. There were plans to rebuild the carriages for a speed of 180 km/h, but this proved too expensive.

The 9x units from this series are converted from A7 passenger coaches. The interior is adapted so that the seat numbering was consistent with the X2 intermediate coaches.

The idea of ​​reserve trains was abandoned after a few years and the carriages are used in regular traffic, including on the Stockholm-Mora route. / Sources: https://www.jarnvag.net/vagnguide/b11
