I6 is the name for a series of carriages of the Belgian railways. The carriages were built from 1977 to 1978 for the national and international train service. The series initially consisted of 20 first-class coaches (A9) and 60 second-class coaches (B11) and are part of the European unit series of coaches purchased by various countries under the name Eurofima. In 1989, 15 second-class carriages were converted in the central workshop in Mechelen into berth carriages with 60 berths (Bc10). During the day, these carriages can also be used as seats, with the lower bed serving as a sofa and the upper beds folded against the wall. The sleeping cars can be recognized by their dark blue color scheme with a pink band under the windows.
