With the wind lashing CTA platforms on Wednesday evening, every minute waiting for a train matters.
"I just saw three trains come by when I was walking to the station. Now I have a feeling I'll have a ten-minute wait," said Aaron Roquena, a CTA rider.
The frigid temperatures tonight a challenge for Metra. Gas heaters were needed to thaw rail switches.
The extreme cold also took its toll on cars. North Side-based Family towing had its entire fleet on the roads helping the stranded.
"Crazy day. Since the weather dropped this afternoon, calls have been coming in non-stop. Tire changes, breakdowns, interstate," said Richard Wishnoff, the owner of Family Towing.
Crews bundled up as they worked on the Wrigley Field renovations, facing unfriendly conditions at the friendly confines.
For Family Towing, the next few days will be busy, but Wishnoff did offer advice for drivers.
"Stay warm. Keep enough gas in your car, and you'll be safe. And if it's time to change the battery, put in a battery when you have an opportunity," said Wishnoff.
