The Regina is a Swedish model of electric multiple unit passenger train, manufactured by Bombardier Transportation (formerly Adtranz). It is used by the national passenger railway SJ along with numerous regional and private operators, in variants designated X50, X51, X52, X53, X54 and X55, and in two-, three-, and four-carriage models. The Regina units are short trains built for local and regional service. The Regina is wider than other Swedish trains; at 3,450 mm (135+7⁄8 in), it allows five-across seating, increasing passenger capacity by 25%. The car body is built of stainless steel, with only bolsters and coupler pockets made of mild steel. The length is 54 m (177 ft 2 in), 80 m (262 ft 6 in) and 105 m (344 ft 6 in), and the capacity 165-294 seats. A variant of the Regina is used in China as the CRH1. Unlike X 2000, Regina trainsets are corrugateless due to eliminate molybdenum content and add titanium instead.

Top speeds of various models range from 180 to 200 km/h (112 to 124 mph). As part of the Gröna tåget ("the green train") project, a modified X52 train set the Swedish rail-speed record of 303 km/h (188 mph) on 14 September 2008;^[2] the goal was to reach 250 km/h (155 mph) in regular service.^[3]

X55, new high-speed train[]

In late 2007 it was announced that SJ were ordering twenty units furnished for inter-city service.^[4] These trains, designated X55 (also marketed as SJ 3000), were delivered during 2011 and 2012, and are used on the routes connecting Stockholm with destinations like Sundsvall, Karlstad and Falun, allowing the displaced X 2000 units to be used instead to lengthen the busy trains running to Gothenburg and Malmö.^[5] These units are four-carriage trains with a first-class section and an on-board bistro; four-across seating. There is an option for another 20 units.^[1]
