Automatische Übersetzung. Originaltext in: EN - Original anzeigen Both "Rheingold" and "Rheinpfeil" services are integrated to the Trans Europ Express (TEE) railway service. As a result, these coaches are no longer dedicated for a specific service and are scheduled to receive the TEE red & light beige livery between 1966 and 1967.

Hence, these coaches started also to be used on other TEE connexions and often during this 2 years period there were TEE trains with mixed compositions of coaches in both colour schemes (the "Rheingold" cobalt blue & light beige colour scheme and the TEE red & light beige colour scheme). / Quellen: http://www.dbtrains.com/en/coaches/epochIII/rheingold-tee/apm

Originaltext in: EN - Original anzeigen In 1976, some changes occurred in the signification of letters designating passenger coaches at the Deutsche Bundesbahn (DB) and the letter "ü" (designating from 1976 onwards: bogie wagons with passage and closed transitions) and "m" (designating from 1976 onwards: wagons over 24m in length for long-distance services) are no longer used together to form the name.
