I've seen these traveling through my town. Seems like a good way to move cargo, though I imagine a trailer frame required to withstand the stresses may be a bit heavier than the road-only version (which would come with a cargo capacity tradeoff). The 1980s versions had the train wheels permanently attached to the trailers. The newer version uses bogeys between the trailers. -Luke On Sat, Dec 5, 2020 at 4:55 PM Peri Hartman via EV <[email protected]> wrote: > But, imagine, self driving or not, having semi trucks line up and drive > over a railway spur.
