A break in a natural gas main in Geneva has stopped trains on the Union Pacific West line.

Construction crews hit a gas main around 9:30 a.m. immediately south of the Route 31 underpass.

Businesses south of the tracks were evacuated as a precaution.

City officials say Metra commuters should check the Metra website for the latest on the schedule.

The city expects the repair to take several hours.

The underpass has been closed for several months as the rail company is adding a third set of tracks.
