FRIDLEY, Minn. (AP) - The cleanup continues at the site of a weekend freight train derailment that shut down the Northstar commuter rail line.

Seventeen railcars and two locomotives on a westbound freight train derailed and damaged a bridge in Fridley on Saturday morning in an area where an overnight downpour had swept away the BNSF Railway track's foundation.

Other trains, including the Northstar line - which runs between Big Lake and downtown Minneapolis and runs Twins game trips to Target Field - have been blocked from using the tracks.

While one of the two damaged tracks is expected to be back in service by noon Monday, the Star Tribune reports a backlog of freight trains that need to get through will keep the Northstar line from reopened until Tuesday.
