The Regina is a Swedish model of electric multiple unit passenger train, manufactured by Bombardier Transportation (formerly Adtranz).

The Regina is wider than other Swedish trains; at 3.45 m (11 ft 3+7⁄8 in), it allows five-across seating, increasing passenger capacity by 25%.

Unlike X 2000, Regina trainsets are corrugateless due to eliminate molybdenum content and add titanium instead.

[3] In late 2007 it was announced that SJ were ordering twenty units furnished for inter-city service.

[5] These units are four-carriage trains with a first-class section and an on-board bistro; four-across seating.
