Thanks to the wife of my Edward Jones representative, Bridgette (Riley) Mitchell, I have items from her grandfather's, William (Bill) Henry Riley, collection to share that I have scanned. Bill Riley and his son Thomas Riley both worked for the Frisco out of Memphis. Attached is a map of the Talkback Speaker (bit it doesn't mean you can, System locations as laid out in Tennessee Yard in October, 1957. It will print to 8" to 12" x 14" paper, landscape format.
Wow, if nothing else, it is an exceedingly detailed map of the Tennessee Yard track arrangement and all of the accompanying buildings. Hope that there is more items to come, Keith. Best Regards,
