Calgary Alberta - CP clean-up crews are clearing debris after two trains collided in southeast Calgary Wednesday night, derailing seven cars.
 
Calgary Fire Department officials confirm the collision occurred just outside the Ogden Rail Yard, south of 50 Avenue S.E., around 20:15.
 
Ogden Road, from 50th Avenue to Millican Road S.E. was closed overnight but reopened to northbound and southbound traffic before 06:30.
 
Fire officials say one of the cars that left the tracks was full of diesel fuel and about 5,000 gallons spilled, but fire crews were able to contain the spill thanks to an existing berm.
 
Crews are also vacuuming grain that spilt from another of the train cars involved.
 
EMS assessed two train crew members on site, but no one was taken to hospital, and no injuries were reported.
 
It's unclear what led to the collision, but CP officials say an investigation is underway.
