Most older fans fondly recall the 4000's.
Built in the 1920's, they served the system well,  carrying
millions of riders into the 1970's.
Open windows, flip-over leather seats and thumping air
compressors gave them a life and personality not found in
modern cars.
Trolley pole operation on the Evanston line was an added
Many of the 6000's were built using components from PCC
streetcars, an early version of recycling.  Some were
equipped with trolley poles for use on the Evanston Line.
The 6000's were the last cars without air-conditioning.
Newer fans know little of the 4000's and earlier cars, unless
they see and ride them at a trolley museum.  To them, and
present day commuters, the CTA subway and elevated lines
are modern, air-conditioned cars.
Newer cars and renovations to other cars have made the
entire front end a cab, which eliminates the "railfan's seat".
But, all things considered, a ride on one of the many lines
can still be an interesting experience.
