Although long out of print (try Amazon or Ebay?), nothing compares to the great volumes I and II of "The Trains We Rode" by Beebe and Clegg published by Howell-North back in the '60's.
Thanks for the tip! It looks like my public library has a copy of this available; I'll go see if I can check it out this week.
Here is a good book ,"Classic American Streamliners", by Mike Schafer and Joe Welsh.
Also keep in mind there were books written about just one railroad, or even just one train, like many books about the 20th Century Ltd, for one example. Let us know about that.
And it was suggested that you look for Official Railway Guides. Good advice!! Now I cannot read your mind, I can barely read mine, so I do not know what time period you would appreciate the most.If it is pure age and pure mileage then I guess anything way back even in the 30's or so would be good.
I have some thoughts of my own, to wit,
1930's, equipment apparently looked pretty much the same. Then the great depression, not much travel. What I have seen from that time period suggests to me that not as many trains had names as do today, or in some cases the same names. A more recent guide might tie in better with more recent train names.
The WW2 years, well yes lots of travel but mostly troop trains, not listed in the timetable. Guess what, the general public was actively discouraged from travel, and I have seen the old ads to prove it, with captions like,"Is this trip necessary? We need this space for our fighting troops." You would not have seen many of us out running around building up our AGR points(so to speak--not being literal here)!!
Diesel and streamlining had been discovered just before WW 2, but production stopped during the war.
The late 40's after the war were exciting times indeed for nearly all industries. The drive for diesels and lightweight streamlined trains began big time. A time of transition. A timetable or guide from here would be good.
But I kind of like the 50's, Major systems still intact. Yet the downslide was beginning but not yet, too seriously, it would advance of course.Some RR's beginning to feel negative but most trains still running...for the moment.And there were still some positives,noted below.
Some bright spots. If you get an Official Railway Guide about 1956 it would include, by then if not before, 1.El Capitan's re-equipping as a high level train, 2. the complete re-equipping of the Denver Zephyr, one of the last trains to be done such,3 the new domes for the Union Pacific, 4.the new trains on both railroads in Canada,5.things I have forgotten.
And something negative would happen November 1957.That was dropping the Dixieland (formerly Dixie Flagler) from Chicago to Miami via Evansville, Nashville Chattanooga,Atlanta,Jak. Some may cry "foul" for me mentioning this since this was the first train I ever rode.
But it is a valid point because this was the oldest direct link from CHI to straight through to MIA, the first of several routes to fall. So, even if I had been born in on Jupiter instead of in Chattanooga, this would still be significant.
The later 50's and 60's I do not recommend because trains started slimmng down in size and many discontinued. The competition from the highway and the air ways, plus the loss of the U.S. mail contract made it more and more depressing.
I say ALL of this to say I recommend mid 50's for buying an Official Guide, for what you will see in it.I think your original interest was purely in mileage rather than the trains themselves But most significant routes still existed in the 50's. But the guides did list mileage which had become freight only. But still sometimes track was abandoned and torn up in later years.
BTW, try to find individual railroad timetables on ebay also.
