German police say a double decker bus carrying dozens of Danish students slammed into a small railway bridge in Munich and tore off part of the upper deck, injuring 40 people, one of them seriously.

Munich police spokeswoman Alexandra Schmeitz said the students, all between the ages of 16 to 19, were hospitalized Sunday. One 17-year-old girl sustained serious head and spine injuries.

The Munich fire department said the driver of the double decker bus apparently overlooked a sign saying the bridge had only a height of 11.2 feet (3.4 meters).

The fire department said the Danish Consulate in Munich had been informed.
