A vehicle includes a cabin and a track assembly. The track assembly is coupled to a portion of the cabin. The track assembly includes a rail assembly. The rail assembly defines an interior aperture. The interior aperture is inaccessible from a top side, a first lateral side, and a second lateral side of the rail assembly. The rail assembly defines a first external channel in the first lateral side and a second external channel in the second lateral side. The first and second external channels receive a carriage power conductor and a carriage data conductor, respectively.
