After a hiatus of five years, the Bielefeld Transport Services mobile opened its doors to the public. More than 20,000 visitors had the chance to look behind the scenes of the depot Sieker. All day long, many of them where queuing at the main attraction: the new city railway Vamos. The visitors used this time to take a look on the attractive design. The generously measured and well appointed passenger compartment met broad acceptance as well.
