When the Rhätische Bahn urgently needed new, modern passenger coaches, it developed the “Einheitswagen IV” series, which was gradually delivered to the line beginning in 1992-1993. The shortened “EW IV” cars can be used both on the main network lines and the Bernina line, and they were used immediately on the Bernina Express. This LGB model is a faithful replica of a second class car, and for service on the Bernina Express, it received red livery with an anthracite coal color stripe across the windows. This LGB model is equipped with metal wheel sets, interior lighting and interior furnishings.
