Line shafts and belts became obsolete when electric motors were developed.
It is hard enough to find pictures of a plant like this, let alone see it running. It appears someone has outfitted a goose-neck trailer with demo equipment to take to antique machine shows. Note that the line shaft is operated by an engine at the front of the trailer since a steam engine or water wheel would be rather cumbersome to make mobile.
