BNSF investigating train crash that destroyed bridge, injured conductors

A derailment of a mile-long freight that injured two crew members overnight is under investigation. It happened in the eastern part of Boulder near Foothills Hospital, close to the intersection of Arapahoe Avenue and 48th Street.

The train workers were taken to the hospital and were released on Friday morning.

The crash destroyed a rail bridge and some trees were knocked down, but there was no other damage aside from the damage to the train cars. The derailment stretches across a a wide area and is expected to take a while to clean up.

Several roads were closed overnight near the crash, including Valmont Street and Pearl Parkway. By daybreak on Friday they were back open.

Some fuel spilled in the crash from a locomotive, but police say they believe none of it made it into nearby Boulder Creek.

Overhead images from CBS Colorado's news helicopter on Friday morning showed several train cars off the tracks and damage to some of the rails.

BNSF Railway is investigating the crash. So far there's no word on what led up to it.

"Crews are on site working to clear the incident as quickly and safely as possible," a BNSF Railway spokesperson said.
