After derailing Wednesday, all remaining Canadian Pacific Railway cars have been up-righted and placed back on the track at the Alyth Yard in Calgary.
Fifteenth Street between Blackfoot Trail and Ninth Avenue will open once response equipment has been moved off site.

The cars carrying a flammable liquid derailed around 5 p.m. MT Wednesday as a slow-moving train was heading northbound out of the Alyth Yard.
There were no leaks or injuries but more than 140 homes were evacuated for a few hours as a precaution.
The product in the cars is a diluent used to thin oilsands bitumen for transport through pipelines.
Fire department officials said Friday they were finding it challenging to remove the product from the high-pressure rail cars.
It had taken crews roughly four to six hours to move the product from each tanker into an empty car on an adjacent track.
Inglewood residents protest CP Rail
Residents of the nearby community of Inglewood gathered outside Alyth Yard Friday afternoon to protest what they said was a failure of CP Rail to share clear information about what CP Rail is transporting.
Roughly 60 people, including the local alderman, attended the gathering.
"We're here because we're fed up and concerned with the absence of information about what CP Rail is transporting," said protest organizer Rebbeca O'Brien.
Many said they are worried about their safety in the aftermath of the Lac-Mégantic tragedy.
Forty-seven people were killed July 6 after a train carrying 72 tanker cars of crude oil derailed and exploded in the small Quebec town.
