A south-bound Union Pacific coal train derailed in southern Denver at 6:30 a.m. this morning between Oxford and Mineral. Some of it's cars fell on the RTD Light Rail right-of-way and a Light Rail car struck the obstruction, derailing the car. It is unknown what might have caused the initial derailment, but cold weather may have been a factor. Santa Fe is closed in the affected area and RTD is using buses to maintain service between the Oxford and Mineral stations.
