Here are two items that will be included in a package car article being researched for TIES. We have two complete package car schedules in the SRHA archives, if anyone can copy or donate anything on the subject they may have, we'll use it in the article.
The Southern Railway directory of Industries which was printed around 1938 has ten pages of the package car routes for the various freight houses on the system.
One fascinating aspect was the textiles package business going from mills in the Carolina's to Pinners Point for both coastal steamship connections and international. Obviously that would have been a significant part of the business at Spencer Transfer, but many mills loaded package cars themselves. If I recall, the main time freight of the era from Spencer NC to Pinners Point VA was named the "Spinning Wheel".
Other important package commodities from the Carolina's were tobacco and furniture. R. J. Reynolds loaded a lot of cars at its plant in Winston-Salem. Some of those routes were destined for off-line freight houses.
