^Wish you had one of those for superliners.
-Joe
I don't know for sure about the superliner, definitely ex-ATSF high-level coaches though. Those were what the Superliners were modeled on so they would give you a good starting point. if nothing else.
I am currently splitting the 780 pages into PDFs by car, and indexing them by their Car Type, AMTK Number, and Ex-Route Number. Once I'm done I'm going to make a thread here or a webpage, I haven't decided which. This is an amazing resource for modelers of many diverse flags, there is another document I found that, paired with this, traces some of these cars I have plans for back through their ownership history. It's really remarkable.
