Railbus - German Railbuses

German Railbuses

In Germany, the Schienenbus was developed in the 1930s to fulfill the need for an inexpensive rail vehicle built to standard specifications on Germany’s Reichsbahn (the predecessor to DB) to meet the demand for cost-effective services on light railways or Kleinbahnen, and the Wismar railbus were pioneers in those days. These were followed after the Second World War by the eventually ubiquitous Uerdingen railbuses which generally ran in pairs and were a predecessor of the modern diesel multiple units.

A number of serious accidents in Germany in the late 1970s involving Schienenbus resulted in the development and specification of larger, more robustly designed diesel railcars. Although these cars were more similar in size to the U.S. produced diesel railcars, they would not have complied with current FRA requirements, and like their North American cousin rail diesel cars, are largely railroad-derivative designs. The DB Class 628 series exemplifies the contemporary German diesel railcar. This type of car replaced the Schienenbus and locomotive-hauled train consists where possible on branch-line and main-line assignments during the 1980s and 1990s. The Schienenbus has virtually disappeared from regular revenue service, but its rail diesel car successors are prevalent. A new-generation DMUs third in succession after the Schienenbus, are now being ordered by the hundreds by its diversity and the variety of modular design combinations.
