BROWNSVILLE (AP) - Canadian Pacific Railway says six train cars loaded with soybean oil ended up in the Mississippi River after a freight train derailed in southeastern Minnesota.

The railroad says about 15 cars derailed around 10 p.m. Tuesday on tracks about three miles south of Brownsville. CP was able to get five cars back on the tracks Wednesday, but says the six cars in the river need to be unloaded so they can be moved without fear of leaking.

CP plans to reinstall the tracks so empty cars can be brought in to unload the cars in the river.

A sheen has been found downstream, which would indicate the presence of soybean oil. CP says soybean oil is not dangerous but a boom has been deployed to contain any release.
