The Bioče derailment was a train crash on January 23, 2006 in Montenegro. At least 45 people, including five children, were killed and another 184 injured. It was the worst train disaster in Montenegrin history.
It occurred shortly after 16:00 local time (15:00 GMT) about 10 km north of the Montenegrin capital, Podgorica on the Belgrade-Bar railway, renowned as one of the most scenic lines in Europe. A local class 412 train carrying around 300 people from Bijelo Polje in the north of Montenegro to the Adriatic Sea port of Bar derailed above a 100 m-deep ravine above the Morača river, into which it fell. Many of the casualties were said to be children returning from a skiing holiday in the north.
According to the Montenegrin Interior Minister, Jusuf Kalamperović, the accident was caused by a failure in the braking system. Minister of Transport Andrija Lompar and Director of Montenegro Railways Ranko Medenica immediately resigned over the accident, and train driver Slobodan Drobnjak was arrested on suspicion of negligence.
