Train service will resume Sunday morning in downtown Minneapolis after a Green Line light-rail train derailed Saturday night.

Three passengers reported minor injuries after the derailment about 8:30 p.m., but no one was hospitalized, according to officials.

In the wake of the incident Metro Transit buses replaced Green Line and Blue Line trains in downtown Minnepolis. But about 12:45 a.m. Sunday, a statement from Metro Transit said “service has been restored between downtown Minneapolis and Franklin Ave Station and Stadium Village Station and trains will resume their regular schedule Sunday morning.”

The westbound train came off the tracks between the Nicollet and Warehouse District/Hennepin stations.

Metro Transit said that its preliminary investigation suggested the train derailed after it hit a concrete object in the track area.

Metro Transit spokesman Drew Kerr said that it appeared that the train hit a jersey barrier, a concrete wall used to separate trains and traffic. Kerr said that Metro Transit had not yet determined why the jersey barrier was on the tracks. Finding an answer will be part of the investigation.

Another investigation is underway after an eastbound Green Line train pulling into the Western Avenue Station in St. Paul struck an adult male on Friday morning. The man was taken to a hospital and is in stable condition, according to Metro Transit.
