    CTA BLUE Line monitoring

    I was wondering if it is possible to set a live audio feed for the Chicago Transit Authority transit like the Blue line control to listen in if there are delays or express trains???

    CTA Radio Frequencies

    I pass through Chicago while going on band trips & vacation. What frequencies used by the Chicago Transit Authority are used the most & what time are they the most active. Also does the Securitas frequency 464.8000 get alot of activity since they are contracted for the CTA.

    Audio Feed for CTA Blue line

    How can you get an audio feed for the CTA Blue line. I would want to listen to this just in case there is an emergency. The CTA do not give us any info on the train and I am type of guy who is interested in what is going on. I do have a scanner and use that but the iPhone is easier to get.
