Multi-modal freight systems, devices, and methods

A freight vehicle, comprising:

• a set of road wheels configured for road traversal;
• a set of rail wheels configured for rail traversal, the set of rail wheels being separate from the set of road wheels;
• and
• an actuation system configured to modify a relative positioning of the set of road wheels and the set of rail wheels to facilitate operation of the freight vehicle according to a plurality of operational modes, the plurality of operational modes comprising:
• a road traversal mode wherein the actuation system causes the set of road wheels to contact a road and causes the set of rail wheels to refrain from contacting the road, and wherein a motor system drives the set of road wheels to facilitate traversal of the road;
• and
• a rail traversal mode wherein the actuation system causes the set of rail wheels to contact a rail and causes the set of road wheels to refrain from contacting the rail, and wherein the motor system drives the set of rail wheels to facilitate traversal of the rail.
