The interior features of the cars sparkle with a modern level of equipment and comfort. The five-part bi-level set offers seating for 465, 70 of which are in 1st class. Twenty-seven trains were placed into service, which are run as units with the numbers 2850-2876. They are used chiefly on the IC Lines 35 (Norddeich – Emden – Münster – Düsseldorf – Cologne – Koblenz), 55 (Dresden – Leipzig – Hannover – Cologne), and 56 (Leipzig – Magdeburg – Hannover – Norddeich).
