The RTD light rail system was delayed Wednesday afternoon for almost an hour after one of the trains struck a pedestrian at the Alameda station.
The pedestrian, a young adult male whose name has yet to be released, was hit at about 3:30 p.m.
The man has been taken to the hospital with critical injuries.
Passengers on the light rail were told that due to an emergency, the light rail systems would be delayed and that buses would be available to transport passengers where they needed to go.
Many passengers complained about not being told the reason for the delays and how there were no instructions given as to where the buses were and when they would be available.
Trains were running again by 4:35 p.m. but were behind schedule for up to an hour later.
