Texte original en: EN - afficher l'original At the beginning of the 1960s, the Deutsche Bundesbahn (DB) organised a survey for travellers preferences and it appeared that about 3/4 preferred compartment coaches while 1/4 preferred salon coaches. Following this survey, the first prototypes revealed 2-seater and 4-seater compartment coaches designed for the Rheingold and Rheinpfeil trains. But the Dutch and Swiss railway companies (countries concerned by the Rheingold and Rheinpfeil services) rejected the idea as they believed the number of seats in each coach was too small. As a compromis, the Deutsche Bundesbahn (DB) developed a 9x 6-seater compartment coach. / Sources: http://www.dbtrains.com/en/coaches/epochIII/rheingold-tee/avm

Each compartment coach has 9 compartments with 6 seats each (54 seats in total) compared with previously 1st class coaches that used to have 10 compartments. The compartments are separated from the corridor by sliding doors and separation walls equipped with large windows. Each compartment is equipped with ceiling lighting and individual adjustable reading lights above each seat. The seats are all individually adjustable. Because the compartments are 2,322 meter wide there is plenty of legroom. The windows are 1,40 m wide.

These coaches were painted in a blue/ivory white colours and were recognisable by their rounded roofs.
