Way back in 2003 Roy wrote to me:
"At the time I worked at Big Canyon, there was a local train which ran from Gainesville, Texas to Purcell Oklahoma, and one from Purcell to Gainesville every day. Which ever one arrived in Dougherty first usually switched out our loads and set in empties somewhere around noon each day. The Santa Fe also ran a night switcher which came sometimes from Gainesville and sometimes from Purcell to switch us at night. The cars were dropped in Dougherty where they were billed to destination and shipped from there. We gave the billing info over the phone to Dorty (our usual short term for Dougherty.) Bills of lading were made up later and taken to Dorty to be signed. The first thing I did each morning was to do a yard check to see the number and kinds of cars we had on hand for loading. Then I worked up a noon switch list, sometimes ordering kinds of cars mixed in depending on estimates of what kind of cars the plant might need. As an example, I might order 3 coal cars, one hopper, 3 more coals and 2 ballast and so on for each track. We asked that the train of empties be made up like that in Dorty to save switching in our yard. Sometimes I actually guessed right and got the various types of cars in the right order. But sometimes one material was produced at a faster or slower rate than I thought and another kind of car had to be switched in. Before I left in the evening, I had to do the same thing for the night switch, or the night clerk had to do it if we were running a night shift. Later I was promoted to Ass't Supt and turned that all over to someone else. It was a mad house sometimes but was also fun. I told you that the most cars I remember loading in one day was 128 but a usual day was somewhere between 65 and 80 cars per day."
(Note: I asked Roy what he meant by "coal cars" and he said that was the term they used to refer to drop-bottom gondolas.)
Under my current operating schedule the quarries at Dougherty and Big Canyon are switched by a twice-daily local freight that runs north from Gainesville (actually, south staging). In addition to its regular consist of empty gondolas, on its northbound run it stops at Ardmore and collects any cars that are for delivery to Gene Autry or Dougherty. When it returns to Ardmore it drops off any cars being shipped from those locations (apart from the loaded gondolas from the quarries, which it takes back to Gainesville.)
When I introduced the current system, the Ardmore/Gainesville local was handling about a dozen cars at the most, and it made sense to have the one train handle all the traffic. Since then I've added more cars and the train is now quite long as can be seen in this photo from my last operating session:
Once the change is implemented, the current twice-daily locals between Gainesville and Dougherty will be replaced by:
(i) a twice-daily turn operating from Ardmore to Dougherty and back, handling all freight apart from gravel loads from the quarries; and
(ii) a morning south-bound train, and an afternoon north-bound train operating between Purcell and Gainesville (acually, between north staging and south staging), switching the quarries as described by Roy.
Following this change I will rebuild the Gene Autry part of the layout so that I can increase the size of the Ardmore Air Base to better reflect the fact that it was a busy air force base during the '50s. This map from Historic Aerials shows the layout of the rail sidings as they were in 1965, by which time the airbase had become a civil facility.
The change will also allow me to add a few more gondolas so I can increase the traffic from the quarries, and to that end I've already bought some Caswell gondola kits:
The images appear to show a variety of cars apart from (possibly) Caswell gons and Hart ballast cars. Right in the middle of the second image there's what might be a two-bay composite hopper. I'll be studying these photos carefully to see what other car types I might be able to add.
Thanks for looking.
