Martin Drapal, spokesman for Czech Rail Safety Inspection, says the train heading from the town of Krnov to the city of Olomouc hit the animals two hours before midnight yesterday.
The damage to the train is estimated at about USD 5,000. Drapal said in a statement today that the train track had to be closed for almost five hours after the incident.
Trains in the country collide with animals from time to time but such a massive crash is exceptional. Authorities are investigating why the cows were on the track.
