CHICAGO — Chicago's suburban Chicago rail agency is canceling trains and reporting delays on the second day of bitterly cold temperatures.
Metra officials are canceling trains Tuesday along the BNSF, Union Pacific West, Union Pacific Northwest and Union Pacific North lines.
A spokesman for the rail service says the trains that are running will make additional stops.
Metra struggled Monday because of snow cover and switching problems brought on by bitter cold, which set record lows in Chicago when the mercury dropped to 16 degrees below zero.
Six passengers were taken to hospitals with minor injuries Monday when a commuter train hit a "bumping post" at a downtown station.
It wasn't immediately clear whether the train slid or if there was a mechanical or braking problem.
