The night train, "Komet" (VT 10 551), was different from the "Senator" though its shape looked similar at first sight. Its livery was notably different. Instead of single Jacobs axles connecting the cars, twin-axle Jacobs bogies were used. The "Komet" was delivered with 7 (2+5) cars from the outset and soon afterwards equipped with an additional dining car. All available online pictures show the Komet with 8 cars (2+6). In 1956, an additional car (conference car 551i) was built for the first foreign journey by a German President after the Second World War. Due to the train's limited power, another car had to be taken out of the train in order to accommodate car 551i. The conference car is the only surviving unit. "Komet" had better driving characteristics than "Senator", which was described as behaving a bit like a goods wagon.
