U.S. railroad company Union Pacific Corp said on Monday that a rail line on which a train derailed in northern Colorado was back in service.

The line, which is used about once a day, connects Windsor, which is in the Niobrara shale play in northeastern Colorado, as well as other towns in the state.

The train, which was heading from Windsor to an East Coast destination, spilled 5,300 gallons of oil on Friday morning.

Mark Davis, a spokesman for Union Pacific, said there were no injuries and the rail line was back in service by Sunday evening. He did not know who owned the oil or its exact destination.

AJOT Followup:

A spokesman for Union Pacific updated AJOT on the status of the situation Monday afternoon:

Crews off loaded the oil from five of the six tank cars. This operation was completed Saturday night.

Crews replaced 80 feet of track and completed some repairs to a bridge and the line was open for rail traffic late Sunday night.

Barring any weather delays, they were going to start removing the soil that soaked up the 5,300 gallons of oil that leaked from one of the rail cars.
