During the final years, I clipped and saved relevant newspaper articles from the Chicago Tribune and the Villa Park Argus.
The Chicago Tribune story of the end of all regular passenger service the next morning, July 4, 1957. Note that wooden cars were used until the end.
For awhile there was still hope.
Freight service didn't last much longer.
Meanwhile the competition was modernizing.
