The story
The first car transported by rail in Germany was carried by the Deutsche Reichsbahn on 1 April 1930. At first only the rich and privileged could afford cars and the market was small. In the 1950s, Britain and France started to run car transporter trains. In the Summer of 1956, the first true car train in Germany ran, via Hamburg, Munich and also Ostend; the drivers travelled in a passenger car, whilst their automobile was carried by the same train. The German economic recovery in the 1960s brought an increase in travel and a corresponding increase in the number of cars transported, increasing eightfold to 80,000 by 1969, many holiday makers travelling to warmer more sunny parts of Europe. The numbers of cars transported peaked in 1973, at 185,550 vehicles; the oil crisis put an end to this growth. In 1978, the Bundesbahn cut back by 40% its number of terminals due to a lack of demand. The increase in car ownership in the 1980s did little to help the rail-car transporter business - changes in lifestyle meant that people often expected to drive their cars all the way to their holiday destination (which represented most of the car by rail business). Additionally, the seasonal nature of the business meant that buying new wagons was not profitable. In this decade the number of people flying over to a holiday overtook those travelling by rail. Also in this decade, the transport of caravans and boats also ceased. After the merger of the Deutsche Bundesbahn and the Deutsche Reichsbahn - in 1996 a new company was formed: DB AutoZug.
