What you have there is an exchanger. What is on top would be blind flanges, one would be a permanent one used to enter the tank, the other one would be were light ends were recovered with another small exchanger were the light ends come through the tubes and outside heated, heavy's would drop down, light ends back to tower ( this small exchanger is not shown on railcar and would and could be transported by other means). There would be tubes in which 400# or greater steam inside would heat on the bottom, with 2 small flange were piping to pumps. Depending if these bottoms and were in the process either asphalt, Bunker, or even bottoms useless to be pumped and atomized with 400# steam to be burned in incinerator creating flyash, which is nowadays mixed in concrete for roadways. Fresh bottoms pumped in from opposite side of exchanger also on bottom. These inlet, outlets would be 4 to 6". So 2 small on bottom, 1 manholes on top, and a blind flange and usually manholes flanges on end . If this helps. Josef, If this is not the exchanger in the video, what is the unit in the depressed car following the main distillation tank. The vessel in the depressed car, would be a vessel/tank (we had a "D" designation for it) mounted horizontal on saddles. bottoms from tower pumped to it and heated before being pumped for asphalt, etc. A small exchanger was mounted on large flange as you have at top were light ends came through (vapors) and piped back to tower to recover any light end products. The small exchanger that sat on top was just that, small, diameter of flange and 4 to 5 feet high. It was removed, maybe junked and vessel was flanged off. The items on this train are good and probable sold to a small refinery or even chemical plant. Piping to tower and vessel inlets, outlets are flanged off to protect junk, etc. from getting into tower or vessel. Sometimes just plywood flanges are used. The insulation has been removed from tower and vessel possible to check metal thickness, welds on outlets/inlets, connection, that's why they look rusty, insulation removed. As to the vessel, we called it whatever its designation was in process, bottoms recovery. Been 15 years, I remember D-803 (the vessel) for a T-901 tower. The operators and myself called the vessel just a Tower exchanger tank. I hope I wasn't to confusing? What came off main tower was further distilled or purified and exchanger were there to recover. As to gasoline we only made 2 grades, low and high octanes. It was the Terminals that would blend for the in-between grade. Aviation Fuel was a probable the critical, since no impurities could be in it and octane rating important. The round tanks you see at refineries or even large Terminals were for Butane and many times metered added to gasoline to increase or bring back to specs for high octane. Many independent Terminals would purchase flat gasoline and add Butane from railroad tank cars to this flat gasoline to bring octane back up rather then burn it off.

Josef,
Thank you for the explanation. It was not too confusing and it is obvious from the video that this was not a distillation tower. or exchanger I am working hard to create, as nearly as I can, the original equipment. The distillation towers will be broken into sections with the man covers and section plating to match the video. there will be numerous pieces of cut welds that held the sidewalk and railing on each piece. I have found parts to emulate the piping and hopefully it will be a good "rendering" of the tower, just like I am trying to make a good rendering of the tank.
I do appreciate knowing what components make up each of these sections and will try to create similar components. I will post pictures of each step as I go. This was your baby so keep me up to date.

Wood, it looks good. I see what you mean about the hangover but as long as it doesn't take out your scenery and structures you're golden. 👍 Hangover?? What hangover? Did I miss a good party?? Gary.

Don't worry Gary, this High Octane party is just beginning..

Your doing good. I like what your making. Thank you, but I do look for your input. You will be very helpful for the rest of the assemblies. I will only do 3 components. The double flat car will hold a 19" scale 72' tower, the depressed car will hold the tank 8" scale 32' and the next to last flat car will hold a 14" scale 60' tower. There will be an empty weighted flat car between each load and at the end of the train. As best as possible, I would like theses to appear realistic and someone with experience would recognize it for what it is. I have found technical drawings of these and as best as I can parts that fit the drawings.

I have found technical drawings of these and as best as I can parts that fit the drawings. If I may. If your going to keep the flanges on top. Nip off the hinges. These would be blinds just and when opened would be removed with a winch attached to an overhead beam by maintenance. On the Tower at each "landing" a smaller sized manhole entrance flange with swing out would be more properly sized. To simulate plywood blinds on many (you can see the yellow on tower), you can slice off half the cover and glue yellow paper stock on top to simulate a wood cover. On top of tower just 3 small piping for relief valve, and small piping for temperature and pressure instrument to send signals down to control room. Small piping on sides would be for instruments, larger sizes for draw offs of towers products. Bottom of tower is rounded (which you can't see because of tower support structure (grey painted with opening for personal/maintenance). Steam would be piped in just above and below the bottom inside coils and condensate trapped outside on exit piping which would be represent by just piping with blinds. But seriously, your doing good and I can't wait for tower to be finished. The flatcar gives a good view and what you add for smaller piping for instruments shouldn't be that important.

Now we're talkin' Thanks Josef!!! I have a few nights before heading for NYC next week. Ordered a few more parts, but I would like to get the small tower made up this week.

Been away for a visit with my NJ family. We saw Celine Dion in the Barclay Center which was a terrific show. Back to the project and I have finished the tank. Not 100% satisfied. I will probably redo this tank. My painting hand is not very good, but practice helps. I just wanted to show some progress. Below are pictures of the base, the painting and my final assembly. These are all Plastruct parts.

Excellent. By the way, we always called the horizontal tank supports, "saddles", be it in transport or at permanent installation site. But, I'm amazed but what you have done. Can't wait to see your Tower.

Your pressure vessel looks great Wood. That's how they looked before they reached their final destination to be installed and fitted.
Gary.

Thank you RJ, Josef and Gary. I feel like I do have a good rendition. This first structure showed me the correct proportions for the addons. I screwed it up with the white paint dabbing. Too much and too sloppy. I will definitely repaint the tank. Then move on to the small tower and the larger tower for the articulated flats.
The video is first class in giving a true picture of these towers and tanks.

A very aggressive project, Wood. I think you are doing a terrific job in making a model of this unique train, certainly one of a kind.
Please keep us posted.
