Via Twitter, Jessi Moth told "Going Public" that in February she saw multiple Red Line trains that had at least one broken door. "GP" asked the CTA about problems with Red Line doors. Late last year, a woman said her stroller was caught in a set of Red Line doors.

The CTA responded: "On the contrary, there has been a decrease in the number of door defects on the Red Line. 
 
In 2008, CTA replaced the sensitive edges on all rail cars in its fleet and have reduced the number of instances of door problems to three percent of all mechanical problems affecting rail cars. However, cold weather can lead to door malfunctions.
 
It is important to remember that like automobiles, CTA's buses and trains have mechanical components that can be impacted by severe weather."
