In the early 1960's, General Motors supplied the CTA with 305 of these "new look" buses, nicknamed "fishbowls" by transit enthusiasts due to the curved windshields. #301 was displayed in downtown Chicago on September 30, 1997, in commemoration of the CTA's 50th anniversary.
Throughout the 1960's, Flxible supplied the CTA with 1,072 "new look" buses of various similar looking types. #3177 was a typical "new look", built in 1965, and now preserved at the Illinois Railway Museum.
The last Flxible "new look" buses were built in 1969, including #3706. This was a group of 30 buses (3700-3729) which were only 96 inches wide, instead of the standard 102 inches. These narrower buses were built for use on the #16 Lake Street bus route, where the elevated rapid transit structure required the use of narrower buses. These were also the last buses from the 1960's to be retired. The TMC 4900 series buses finally replaced them on Lake Street in 1991. Bus was displayed in downtown Chicago on September 30, 1997, in commemoration of the CTA's 50th anniversary.
Throughout the 1970's, General Motors supplied the CTA with 1,870 of these "fishbowl" buses, all of which were retired by early 1996. #9640 is on the #73 Armitage route, at its former east terminal at Clark St. and Wisconsin Ave. This bus retained its original green and white paint scheme until retirement.
From 1994 to 1996, the CTA Green Line elevated route was closed for renovation, and additional buses were needed to establish temporary replacement express bus routes. The CTA leased 33 GM buses which had recently been retired by Pace, after having operated on the Pace South Division. Those buses were repainted in the current CTA scheme, although the white front end and the blue stripe at the roof remained from the Pace paint scheme. These were from a group of 55 buses originally built in 1973 for South Suburban Safeway Lines, which later became the Pace South Division. The original numbers were 701-755, and the CTA retained the same numbers. This is #746, shown on Clark St. at Wacker Drive, at the beginning of the #24 Wentworth route.
