In the year 2000, Alstom presented a multiple commuter train unit called Lirex (Light Innovative Regional Express), which was exclusively equipped with independent single-wheel chassis. Based on the experience with this prototype, the "Coradia Nordic" trainsets for Sweden were developed, which were delivered from 2005 onwards and had "classic" Jacobs bogies instead of the single wheels. The "Coradia Continental" trains were adapted to the smaller Central European profile. The first of these units were delivered in 2008 for the regional trains network around Augsburg. Since then, the trainsets were ordered by several operators. The trains delivered from 2014 got a new, crash-optimized front.
