The "LINT" is a single or multiple unit articulated railcar, which was designed by the german manufacturer Linke-Hofmann-Busch (LHB) and built from 1999.
Since 2011, a further developed version with two bogies under each part instead of Jacobs-type bogies and a modified head design is in production, photos of these vehicles called LINT 54 and 81 are available
