Thunberg doesn't fly on planes because it's considered harmful to the climate. Last week, she was named Time magazine's Person of the Year for her efforts to prod government and others to take faster actions in fighting climate change.

Deutsche Bahn, which used to be famous for its punctuality, has come under fire in recent years for delays, last-minute train cancellations and expensive ticket fares.
