German rail operator Deutsche Bahn said Monday it has filed a new suit against Canadian train maker Bombardier over "serious defects" in trains used on the suburban S-Bahn rail network in Berlin.
Deutsche Bahn said in a statement it is claiming 350 million euros ($455 million) in compensation from Bombardier Transportation Deutschland because it has had to replace the wheels and wheelset axles of the trains and also modify or replace braking systems and the traction motors.
"Over the past months, Deutsche Bahn has tried to reach an agreement by way of an amicable settlement, but to no avail," the company complained.
"Following the expiry of the standstill period, we have now opted to clarify our claims in court," it said.
Deutsche Bahn is already suing Bombardier for 160 million euros in compensations in lawsuits filed in Munich and Berlin over problems with more than 200 regional trains operation in southern Germany and problems with the brakes in regional and local trains in Munich.
Bombardier, alongside rival Siemens, is the most important supplier of trains to Deutsche Bahn and primarily supplies local and regional trains.
