CHICAGO -- Thunderstorms and heavy winds pounded the upper Midwest Tuesday night, stranding Chicago commuter train riders for hours, forcing the cancelation of hundreds of flights, and temporarily delaying Vice President Joe Biden's return to Washington after a fundraiser.
Michael Gillis, spokesman for the commuter rail Metra, said one outbound commuter train was stuck for about five hours when a storm knocked down a power line onto the rail. After 2 a.m. CDT Wednesday, the train was headed back to downtown, and passengers were being asked to find alternative transportation or wait even longer for another train.
Two inbound trains also remained stranded before dawn Wednesday, though Gillis said one had no passengers aboard and the other had few, if any.
There were numerous other delays and cancelations on the rail line due to the severe weather.
"Since the wind stopped, we've been dealing with various track obstructions," Gillis said.
