The green light given to restart the CTA Yellow Line

The CTA yellow line is back on the move. It was shut down on November 16th after dozens on board were injured when a train hit a snow removal machine on the same line. An NTSB investigation is on going and the cause of the crash in still not determined. Since the crash train speeds have been reduced ad communication cleaning of the rails has been improved. The final NTSB report expected to be released later this year.
