Trafikverket WL6 5610 (S-TRVF 50 74 747 3004-4). One of 23 sleeping-cars built 1993 to 1994 by Kockums, with 13 three-berth compartments, two toilets and a shared shower. 20 of them are owned by Trafikverket (earlier SSRT) and currently rented to Vy for trains between Stockholm and Luleå/Narvik. With a higher capacity than the WL4 they offer a more affordable class.
