The Rhino Liner is an E-Series robot that appears the Rail Canyon and Bullet Station stages of Sonic Heroes. It strongly resembles the E-02 Rhino Tank, but this robot is confined to travelling on rails. This automated locomotive patrols the rail tracks of Dr. Eggman's weapons depot, blasting intruders with the cannon on its back. The Rhino Liner will explode if it runs out of rail, though it can switch to an adjacent rail if one is available.
