I was at the INHS this afternoon leafing thru some scrapbooks of clippings from several newspapers (Hammond, Bloomington, Greencastle, and others).
The named papers said that #5 & #6 stopped running account of the coal strike about December 5, 1946 effective on a Sunday. Trans #3 & #4 were unaffected. It's interesting that the day train was annulled and the nightrain continued.
Interestingly the same thing happened on March 1, 1945 when the Office of Defense Transportation ordered passengers trains with less than a minimum number of passengers to stop operating. This in addition to #5 applied to trains #35 & #36 (Chicago-Indianapolis, AKA Mid-Nite Spl.) and #19 & #28 (French Lick-Orleans)
I did not make very detailed notes as the 5th (date on the articles) was a Thursday.
I also remember a brown out caused by that strike while I was in grade school.
