Grain handling has changed since the 1981 film.
The film showed a straight truck with about 300 bushels , manual book keeping,loading a box car, and a host of OSHA violations. An old grain elevator is a dangerous place. Grain dust is very explosive. Also, there are hundreds of confined spaces. One example is the operator going down a shaft to grease a bearing
with dust falling down on him and his light bulb, which looks like the proper enclosed unit.
Did you cringe , as I did,when you saw the car pincher? Guess where the car wheel in going if the guy falls and the car rolls back.
The small country grain elevator is pretty much history. Todays operations have automated grain sampling and accounting . They can dry and store hundreds of thousands bushels. They can load out a unit train in a few hours rather than one box car at a time which takes almost constant attention to keep the grain load level.
Todays grain terminals have a dump pit that will hold nearly the entire 950 , or so, bushel load from his semi truck
