What I know about Red Line slow zones
My pal KevinB asked about the status of Red Line slow zones after the CTA completes the subway slow zone work in October. I haven't yet asked the CTA about that, but I did review the most current slow zone maps. Here's what I can tell you.
According to the map below, almost 13,000 feet of slow zones between North/Clybourn and Clark and Division should be fixed in October.
So, this map indicates October should mark the end of slow zone work in the Red Line subway.
And what about other slow zones north of the subway? The map below shows we're all clear from Armitage through Belmont. The next slow zones are centered around the curve at Sheridan.
Take a look at the big map to see some slow zones exist from Thorndale to Howard.
