BERLIN (Reuters) -German rail operator Deutsche Bahn plans to cut 30,000 jobs, or around 9% of its staff, it said on Thursday, after huge investments to repair its rail network, strikes and bad weather led to a billion-euro first-half net loss. The cuts are to be made over the next five years and mostly affect administrative jobs, Chief Financial Officer Levin Holle said, adding this year around 1,500 jobs would have to go. Deutsche Bahn reported a net loss of 1.2 billion euros for the first half of this year, confirming an earlier exclusive report by Reuters.
