But close inspection of old issues of the "Official Guide Of The Railways" will reveal a number of old obscure commuter trains in cities outside of Chicago, all of which were eventually discontinued. Most commuter trains operated during rush hours only.
In Pittsburgh, the Pennsylvania Railroad had perhaps the largest commuter railroad operation in the country to be completely abandoned.
Included is schedule information from the January 1930 and June 1942 Official Guide. Generally, only trains dedicated for commuter service are listed. Although many lines had various other trains operating over longer distances, which could have been used as commuter trains.
Additional Cities With Commuter Trains
In 1901, these additional cities had commuter operations.
The Official Guide Of The Railways over the years, normally listed commuter trains as well as intercity passenger trains. Notable exceptions were in the Chicago area, which were Burlington, Chicago & North Western, Illinois Central, and Chicago & Western Indiana. Around the 1960's, most other railroads with major commuter operations stopped including those schedules. It is possible that some of these obscure commuter operations continued longer than noted, while no longer being listed in the Official Guide.
