BERLIN (Reuters) - Trains on a busy German route were delayed for four hours after a train driver hit the emergency brake fearing a man next to the tracks was trying to kill himself -- but he was only picking blackberries.
Authorities stopped all trains and closed the track, causing a chain reaction that delayed 11 trains for 4-1/2 hours.
Police said on Wednesday the 70-year-old was spotted as he leant over the track near the western city of Cologne but it turned out he was just trying to reach the best berries.
