Frack sand was (is) hauled this way big time as well. There was an outfit trying to break into frack sand using what seemed to be similar to 20' intermodal containers, my brother was talking about that a lot in the last couple of years that he was doing oil field pneumatic hauling. Seemed to be a more efficient method. No real extensive driver down time to load or unload - like picking up a railyard load - the box gets dropped on your chassis and you haul it to the site where they lift it off and give you an empty to haul back.
Frac sand is still hauled in pneumatic trailers as well as the boxes. The boxes are about 10 ft long and 8 ft wide and hold an average of about 42k lbs. The one in the picture is the provider I am currently using on a five well pad in the Permian Basin. Yes, the name of the company is "Sand Box". There are others using this method as well, with slight variations (due to patents) in how they work and capacity. In addition to the pneumatic and boxes, the third method is hauling sand in belly dumps. I immensely prefer the boxes. They produce a lot less dust than pneumatic transfer, and, as Mr. Curmudgeon mentions, there is little downtime to get them offloaded on location. It is done with a (really big) forklift in less than 5 minutes.
Transporting freight using two or more transportation modes. An example would be freight that is moved by truck from the shipper's dock to the rail yard, then placed on a train to the next rail yard, and finally returned to a truck for delivery to the receiving customer.
In trucking when you hear someone refer to an intermodal job they're normally talking about hauling shipping containers to and from the shipyards and railyards.
Sand Box, that's the name of the outfit he was talking about! Thanks, Bush Country!
He was really looking forward to getting on running those, as his down time was killing him on the pneumatic tank runs.
He spent a lot of time in the Permian running sand, and loved it. Miss his story time calls with leading off with "You're NOT going to believe what I saw out here today..."
