New schedules for the CTA's eight rail lines go into effect on Sunday.
I'm not sure the schedules are worth the millions of pixels required to publish them on the Internet. Perhaps the CTA is required to publish them. Admittedly, they are useful for those ride very early or very late to determine when the first or last train leaves for the lines that don't operate 24 hours.
But if you really want to know when a train will arrive at your station, use CTA Train Tracker.
