The Freight Shuttle Xpress (FSX) concept was initiated at the Texas A&M Transportation Institute for the purposes of finding a low-emissions alternative to moving freight and relieving congestion created by trucks in heavy freight corridors. The Freight Shuttle moves truck trailers (up to 53 ft.), domestic intermodal containers (up to 53 ft.), and all sizes of ocean shipping containers via emissions-free, electric-powered transporters on elevated guideways in the medians of highways or other rights-of-way over distances of up to 500 miles.
