Germany's national railway said it is taking part of its high-speed train fleet out of service after a crack was found in an axle. The move is likely to cause disruption on several major routes, AP reported. Deutsche Bahn AG said nearly all the 70-strong fleet of ICE-T trains will be idled starting Saturday for safety checks. It was unclear when they might return to service. The trains' tilting technology allows them to lean into curves and take them at a higher speed than ordinary trains. An axle crack was found earlier this month and Deutsche Bahn stepped up the frequency of safety checks. The rail operator said Friday that it is moving to sideline the fleet after the trains' manufacturers gave it only «unclear information» on the axles' life span.
