Winnipeg Manitoba - A train derailment has shut down a bridge that links Winnipeg's north and south ends.

Police say six cars of a Canadian Pacific freight train jumped the tracks in the CP Rail switching yards Saturday night, breaking two support beams on the Arlington Street Bridge.

Last month, the same bridge was shut down for about a week after seven cars jumped the tracks, damaging support girders.

These latest repairs are expected to take at least a week.
