Texas oil field 1918

I thought this was a neat photo - it has a wide variety of the elements associated with an early 1980's oil field.  In addition to dozens of oil derricks it shows the railroad connection with an interesting variety of rail cars.  There is a stock car, a ventilated boxcar, a standard boxcar, and a reefer car.  Also several buildings - perhaps the long one by the boxcar is a freight station.  There also seems to be a lot of buildings among the derricks.

There are also a number of vintage automobiles, but no trucks - just lots of wagons.  I do not see any indication of what they used to transport the oil.  Early tank cars were often just short vertical tanks on flat cars.
