A local traffic legend - known as the Blutblase (blood blister), Ferkeltaxe (piglet taxi) or simply Schienenbus (rail bus). In 1957, EB Waggonbau Bautzen produced the first prototype of what was to become the universally familiar rail bus. Over the course of the 1960s, it evolved into the undisputed number 1 on side lines of the DR. Thousands commuted daily between their homes and workplaces � using the �Ferkeltaxe�. In 1959, Waggonbau Bautzen unveiled a second test vehicle. Now the rail bus featured a diesel engine that was twice as powerful as the first prototype, at 180 hp. The VT 2.09.1, which was implemented in 1965/69, was distinguished above all by the multiple control system of the basic model. Now it was possible to drive two engines from one driver�s cab
