Attached is Terminal Facilities and Operations - Memphis, a sales department tool to describe the Memphis Terminal and its operations (1960).
Excellent aerial overview of the yard, plus detailed map. And, it kept getting better. I found the sequence of operation in handling trains through the yard on p. 20 quite interesting. The next best thing to being able to interview those who would've worked in the yard back in that time. Perhaps my favorite line in the whole document is how "Control of the [hump yard] retarders at Tennessee Yard is by an electronic 'brain' (analog computer)." Best Regards,
