On October 31, 1993, CTA opened a new 'L' line from the Loop to Midway--the first completely new 'L' line since the Dan Ryan Line (today's South Side Red Line) opened in 1969, and the first time the 'L' was extended into a part of the city previously not served since 1984 (when today's Blue Line was extended to O'Hare).

DOWNTOWN — The CTA has unveiled a new Instagram page devoted to old-school photos of days, trains and buses gone by.

The Instagram page, which features old-school photos of CTA trains and buses, debuted in honor of the CTA's 70th anniversary this year.

“For 70 years, Chicagoans have turned to the CTA to get them where they’ve needed to go,” said CTA President Dorval R. Carter Jr. in a news release. “Our 70th anniversary gives us the chance to not only look back at our proud history, but also to look ahead to the improvements and investments we’re making to serve customers for another 70 years.”

CTA began operations on Oct. 1, 1947, taking over operations by the Chicago Rapid Transit Company (which ran the ‘L’ system) and the Chicago Surface Lines (which ran the streetcar system and some bus lines), according to a release.
