Germany's Deutsche Bahn expects the government's 50 billion euro climate change package to generate the railway company's biggest growth spurt in its 180-year history, the state-owned firm's boss said on Sunday. In a telephone press conference, Richard Lutz said the measures announced on Friday, including a cut in value-added tax (VAT) on train tickets, would give it an additional 20 billion euros in revenue by 2030. The company planned to buy 30 new high-speed trains by 2023 to cater for the expected growth in passenger numbers, a one billion euro bonanza for train-building companies.
