The defining feature of the RoadRailer is that it is a bimodal trailer with two sets of wheels. This unique design allows it to operate seamlessly both on highways and railways, enhancing its versatility for transportation. The dual-wheel system enables the trailer to transition from being towed by trucks on the road to being transported on rail cars without the need for extensive modifications or separate equipment. This capability provides significant logistical advantages, including efficiency in moving goods over long distances while taking advantage of both road and rail infrastructure.

Options that suggest the RoadRailer has multiple loading compartments or can only be towed by trucks do not accurately represent its functionality. Additionally, while it can operate on rail, the opportunity to use both modes of transport is what sets it apart distinctly. This characteristic of being a bimodal transport solution fundamentally defines the RoadRailer.
