Austrian officials said the crash occurred on a section of track used by trains traveling both directions.
VIENNA — More than 41 people were hurt - five of them seriously - when two crowded commuter trains crashed head-on in Vienna during the morning rush hour on Monday, authorities said.
The driver of one train and another person remained in critical condition after the collision occurred in an outlying Vienna suburb where trains in both directions use one set of rails.
Rescue crews were on the scene shortly after the accident and evacuated all the passengers and crew.
Operations on the line had been switched to manual following a technical defect with a shunting switch, and a spokeswoman for Austrian railways said human error had not been ruled out as a possible cause of the crash.
"A train got permission to travel when it should not have," she said.
