One of the many railroad books I own has a pictures, where the hand written Train Board of Chicago Union Station is visible in the background in the early 1940's. I don't know the date of the photo, however, various trains - from both the East & West were showing serious delays.
Us old timers always believe 'it was better back in "our" day'. Then reality intrudes. As a kid in the late 50's & early 60's I would make a trek to All Nation Hobby Shop in Chicago on a near monthly basis, and would make the rounds of all the Chicago passenger stations - when winter hit, trains got late, and not just 15 or 20 minutes or so.
