The official word on CTA rail and bus enhancements
Last week I reported exclusively that service on the Red, Brown and Purple lines would increase starting today now that all four tracks are finally open at Belmont and Fullerton. In that thread, Ryan asked for a link from the CTA site about this. Well Ryan, the CTA finally posted about it, and I'm happy to oblige you here (link now fixed).
That CTA posting also mentions quite a few bus service enhancements, including for #9, #91 and #143. So be sure to check those out.
