Dozens of people suffered minor injuries in a train accident in Salzburg, Austria, police said Friday. The accident occurred when additional cars were being attached to a stationary train and were apparently driven in at too high a speed, officials say. The accident occurred at 4:46am, rail operator spokesman Robert Mosser said. Police spokesman Michael Rausch said 35 to 40 people reported injuries, none considered serious, according to AP. The cause of the accident is under investigation.
