The CTA took over operation of the city's public transportation system from the Chicago Rapid Transit Company in 1947, giving residents a new abbreviation to gripe about for years to come. But as much as we complain about station closures, late buses and Ventra fiascos, it's pretty incredible that a system this large runs at all. Even more impressive is the fact that the El has been ferrying people to homes, offices and restaurants since 1892. We looked through the CTA's photographic archives and picked out some of the best historic images of Chicago's ever-changing fleet of trains and buses.
