Police said firefighters were checking people on the train for injuries.

“It is unknown at this time if drugs or alcohol were aggravating factors relating to this crash,” officials said.

Officials said there were 43 people on the RTD train — two of them were evaluated by medical personal but not transported to the hospital.

Traffic Unit Investigators will continue to investigate.

“Part of the investigation will include working closely with RTD to obtain and review surveillance camera footage from the intersection to determine if the level crossing signals and lights/audible bell were functioning properly,” officials said.
