A vehicle system comprises an interface assembly and a controller both on board a first rail vehicle. The interface assembly comprises one or more mechanical couplers, fuel couplers, fluid couplers, and electrical connectors, to detachably couple the first rail vehicle to a separate, adjacent fuel tender vehicle, for the transfer of one or more of fuel (e.g., compressed natural gas) from the fuel tender vehicle to the first rail vehicle, heated fluid from the first rail vehicle to the fuel tender vehicle (e.g., for regasification of liquid natural gas stored in the fuel tender vehicle to the compressed natural gas), or electrical power and / or control signals between the first rail vehicle and the fuel tender vehicle. The controller is configured to at least partially control operations of the first rail vehicle in relation to interfacing with the fuel tender vehicle for fuel transfer, heated fluid transfer, etc.

An autonomous transport system is disclosed, formed by four main subsystems: a channel subsystem; a vehicle subsystem; a wheel guide subsystem and central control station subsystem. The system is designed for the transportation of people or goods, to be used in tall buildings and in small and large scale urban environments. It comprises unitary vehicles that may move in different directions: horizontal, steeply sloped and also vertical tracks, thanks to novel traction wheel assemblies that roll on carefully designed wheel tracks. The system's cabin maintains the horizontal level / position regardless of the changes of track direction or slanting thanks to pendulum based automatic level control and may rotate up to 180° under normal conditions and even a full 360° turn respect to the wheel assembly in space restricted positions. The cabin is mounted on a cantilever, thereby displacing its center of gravity respect of the wheel guides. Thus, a lever action is established, which presses the wheels against the wheel tracks and therefore enough frictional resistance is obtained so as to avoid wheel slippage on the wheel tracks. The vehicles are moved by non-polluting, electric drives that move and stop them with high energy savings. The vehicle runways are designed taking in account safety features against fire hazards. Several vehicles may be used at the same time and on the same track and may run individually or in groups, conforming a train. The system allows for vehicles to be parked in bypassed positions or else they may be disengaged from the convoy to be used individually.

A load-lifting apparatus has one or more prime power sources, one or more energy storage systems and regenerative braking. Regenerative energy is recovered when the load-lifting apparatus lowers its load. The elements of the prime power sources, energy storage devices and electrical components may be distributed to provide stability for the load-lifting apparatus. The general power architecture and energy recovery method can be applied to cranes, rubber-tired gantry cranes, overhead cranes, mobile cranes, ship-to-shore cranes, container cranes, rail-mounted gantry cranes, straddle carrier cranes and elevators. In such an architecture, the energy storage system helps alleviate the power rating requirement of the prime power source with respect to the peak power requirement for lifting a load.

A hybrid energy railway vehicle system having a traction motor with a dynamic braking mode of operation for dynamically braking the traction motor and for generating dynamic braking electrical energy and an electrical energy storage system that is in electrical communication with the traction motor and that stores dynamic braking electrical energy generated by the traction motor. The system also has a hybrid energy railway vehicle with a plurality of wheels wherein the traction motor has a motoring mode of operation for driving one of the wheels in response to electrical input energy. A converter selectively provides stored electrical energy from the energy storage system to the traction motor as electrical input energy for driving one or more of wheels. The hybrid energy railway vehicle is optionally equipped computer readable medium having computer executable instructions for controlling the operation of the hybrid energy railway vehicle and a processor configured to control the operation of the railway vehicle as a function of at least one of a plurality of operating modes.
