Decal on a Cincinnati Car Company-made 4000-series train car; this model in particular served the CTA from 1923-1973. The CTA brought this car out this past weekend at an event to celebrate 100 years of service to the Linden stop in Wilmette, IL.

Edit: Also, what is that beautiful font? Futura?

This photo, just two months after it opened, shows the Belmont station on what is now the O’Hare Branch of the Blue Line, with two Douglas-Milwaukee “B” trains berthed in the station. The station opened on February 1, 1970 as part of a new subway to connect the Logan Square ‘L’ (opened in 1895) to the new expressway median line in the Kennedy, terminating at Jefferson Park. The line would later be further extended to Chicago-O’Hare International Airport (ORD). (via CTA Flickr)

The L station I use most often turned 42 today.
