Re: Oil extraction

Fascinating photos--thanks Doug. Some tanks had a "steam jacketed outlet" (ACF's name, illustration in 1925 CBC) that heated the valve and outlet pipe area. It looks to me like the small trailer had a pump on the far end that sucked the oil out of the dome, through the pump, and into the truck. The heavy (insulated?) hose to the outlet area could be the heating line, with the hose through the dome poked down into the outlet area to suck up the warmed oil. So the other apparatus on the trailer would be water and fuel tanks, and a small boiler. Informed speculation, tear it up Tony ;)
Peace, Rick Aylsworth

Group I have posted the two photos that started this thread, per Clark's
question. They can be found (when approved) in the photo album MSTL. The
photos were taken by Vern Wigfield in June of 1954 in Marrietta MN, on the
M&StL. Vern has given me permission to share his photos.

The photos show URTX tank car 56816 being unloaded, via a pump trailer into
a tank truck. There is a hose into the dome as well as from the bottom
