Hanover (dpa) - Due to a technical problem on an ICE on the way from Berlin to Cologne around 250 travelers had to change trains in Hannover. The cause of the disturbance is still under investigation, a railway spokesman said on Tuesday.

With about three hours delay, the train travelers could continue. On other train connections, the breakdown had no effect.

On Twitter some passengers complained about the long waiting times. "Passengers thirsty, no supply of drinks," wrote a user. Others praised the employees of Deutsche Bahn for their commitment. "Midnight. First car evacuated. Respect for the employees of #Bahn. They are already totally through, but stay calm and professional, "wrote one concerned.

The train had been left on the way from Berlin to Cologne in Hannover-Leinhausen near the main train station. The train first tried to tow the train. When it became clear that this was not possible, the passengers had to leave the broken train via ladders.

Among them was Federal Transport Minister Andreas Scheuer (CSU). He was on the way to the metal working fair Emo in Hanover. His communication manager answered via Twitter: «Today # ICE-malfunction after the start. Now we are sitting in another - crowded - after #Hanover ».
