Re: Oil extraction

Clark are you referring to the photos of UTLX 56816 being unloaded on the
M&StL at Marietta MN in June 1954? The photo shows two tank cars next to a
grain elevator, and the Pacific Grain Co coal sheds in the distance, with
hoses connected to a trailer, then to a tank truck next to the trailer. If
so, the photos were taken by Vern Wigfield, and show the transfer of oil
used to control dust on gravel roads. Not sure about 1954, but in later
years road oil was often used motor oil. Not a consistency that would need
steam to make it flow.
