In 1990, after a delay of several years, the IC3 trains came into use, initially as "lyntog", and in 1991 as ordinary intercity trains. The IC3 trains, being a specimen of the Flexliner type of multiple units, have a distinct appearance due to the rubber-framed ends, allowing access between trainsets when coupled together. The re-engined Flexliners are now (2014) nearing the end of their service life, but due to problems with the Ansaldo Breda built successor class IC4 they are expected to remain in service for another five to ten years.
