Abstract
A truck trailer system including a connector vehicle with retractable wheels that are designed to engage with a railroad track is provided. The connector vehicle includes main wheels and at least one pair of secondary wheels, and an actuator assembly operably connected to the pair of secondary wheels. The actuator assembly is designed to actuate in a first direction to extend the pair of secondary wheels to engage with the railroad track, and in a second direction to retract the pair of secondary wheels to disengage with the railroad track. The truck trailer system may include a reinforcement assembly comprising at least one cable provided within a conduit, for connecting multiple units to be pulled at the same time via truck or locomotive. In embodiments, the reinforcement assembly may enable hauling of at least 10, or up to about 50 units via a single locomotive.
