Two freight trains collided and derailed in Boulder, Colorado, on Thursday night, causing damage to a bridge, spilling fuel, and injuring two crew members.

The crash occurred near Boulder Community Hospital, prompting road closures for several hours while authorities investigated and cleaned up the fuel spill.

The trains, including locomotives and several cargo cars, sustained significant damage, and crews are working to clear the wreckage.

The cause of the collision is under investigation. The injured crew members were treated for minor injuries and released, the Associated Press has reported.

Although some fuel spilled, it did not contaminate nearby Boulder Creek. The crash also destroyed a rail bridge and caused power outages for about a dozen customers.
