Except that tank cars are generally designed for particular commodities, although some liquids like gasoline and diesel fuel will be shipped in general service tank cars.
Would the open hoppers be a empy in load out situation? The birds eye view really gives great detail, I had no idea the coker was there as the Arkansas river paralells that side of the refinery and is not accessable at all. I love the arial photo sites for research.
This thread was initiated by myself quite sometime ago and since then I have steadily been adding to my tank car fleet with mostly Atlas and Walthers 17k and 23k cars, but have also decided to add 33k LPG cars to the fleet so I can represent LPG production. While I don’t see any in the referenced photo’s at this particular refinery in Tulsa, I am sure it would fit in the operating scheme just fine. My original goal of modeling a large industry is still on track, but I have pulled by my initial plan to model approximately 8-10 loads per day because the original plan would have overwhelmed my layout operating scheme.
That explains the occasional hopper I see in the General Merchandise trains on the BNSF in and out of Tulsa.
Now all I have to do is compress all of it to fit. Still working on the track plan for that area so far all I have is a long spur that the cars are setout on.
