In the mid-1950s, the DB developed a new railcar because its predecessor was too weakly powered. These railcars are generally referred to as Uerdinger railcars. The railcar had buffer pads and standard couplings so that it could carry freight wagons, for example. It could also be attached to other trains and transported.

The railbus in the museum was put into service in 1960 as VT 98 9744 and was based in Gießen, Limburg and Siegen. In 1968 it was renamed 796 744-1. In 1995 it was taken out of service and acquired by a private person. It is stored with us.
