I have a company calendar from BNSF and the picture for the month of July is of a “sulfur extraction train” from Houston on it’s way to Colo.
It’s got a single GE Dash 9 for power but the rest of the train is sort of weird. All total there’s about seven cars, all flatcars except for a large drum like cylinder with some kind of control cabs on either end of the drum. This flat car with the drum is cut in behind a caboose mid-train and an empty flat car is cut in behind the drum car with a (bay window?) caboose on the rear.
Anybody know where this train is going and what it does or how the extractor operates?
I think it would be interesting to watch it do it’s thing.
