MrFSS - Tom,
Many thanks for clarifying the photos. I had somehow mis-understood and thought they were all from Chicago, thus part of my confusion. (esp. slide 16)
As to the "mystery car" in slide 26 I strongly suspect that is "Katy" (i.e. established nickname for the Missouri-Kansas-Texas Railroad). It would be a little far from home but that was not unusual in the days of the pullman company. Sleepers were frequently switched around all over the country as needed for extras, special movements, temporary replacements for bad ordered cars, etc. , as you no doubt realize.
Since it and the car to the left are both heavyweight, I kind of wonder if that really was the Broadway. I know steamliners sometimes had heavyweight equipment mixed in, but I sort of thought they protected the Broadway a little better than that. But, after all, I did not exactly get to see the Broadway every day so I could be wrong.
As to slide 49 being a Pennsy car on a C&O train, didn't C&O interline with Pennsy say, between Cincinnati and Chicago? I could be all wet, not sure.
As to slide 90 I found myself squinting and getting really close to the screen and I think it says " San Francisco Chief".
Anyway, thanks muchly for the glorious memories. I, too, remember when you could wander around with abandon all up and down the platforms at the stations in Chicago. Guess you remember the old Parmalee(spellling?) taxi , van, etc transfer service between the big major downtown stations.
BIll
