No trains could operate either way due to the track condition. At 10:00&nbsp;PM on that day, an emergency closure of the Yellow Line was called. Yellow Line service returned on October 30, 2015, with the CTA offering free rides for one week and free parking at the Dempster-Skokie Terminal through the end of 2015.
