Pågatåg rolling stock under the first concession (1983–1997) were primarily of type X11 (with diesel Y1 railcars used on the then-non-electrified Malmö-Ystad line from 1990–1996), but as demand grew, other available train types had to be added to the roster. Some Bombardier Regina X52 type trainsets were rented from other train owners. The type X31, normally used for the Øresundståg traffic to Denmark, was also used sometimes. Subsequently, Skånetrafiken ordered 99 new Alstom Coradia X61 sets, a variant of the type used in Stockholm. Several of them have been used on revenue services since August 2010, and since 2013 they have taken over all services. Skånetrafiken attempted to sell most of the X11 trains during 2011, since they can no longer be used; they do not fulfill all the safety requirements for the City Tunnel in Malmö and had only a temporary exception from the rules.
