Power system for locomotives
A train includes a fuel storage tank configured to contain liquid fuel, a locomotive including an engine having an intake and configured to combust the fuel in a combustion reaction to provide a power output, an oxidant storage tank configured to contain at least liquid oxygen, and a vaporizer disposed along the flow path between the oxidant storage tank and the intake. The vaporizer is configured to convert a portion of the liquid oxygen into a flow of gaseous oxygen and provide the flow of gaseous oxygen to the intake thereby increasing the power output of the engine.
Device for energy supply of trains
Device for energy supply of a train set consisting of at least one hybrid- or diesel-electric locomotive. The device comprises at least one gas driven electric power generator, driven by at least one engine or fuel cell which in turn are driven by gas from the at least one container or hydrogen storage facility, wherein the at least one electric power generator is connected to the locomotive electrical power supply networks. The device is arranged for supplying the train set with electrical current supply and/or idle current for a locomotive provided with or without automatic idle stop.

Rail cars for transporting heavy hydrocarbons
A method and system of temperature control of heavy hydrocarbons in a consist of rail cars is disclosed wherein waste heat from one or more of the locomotives propelling the train is utilized to heat the heavy hydrocarbons in a consist or ambient air is used to cool the heavy hydrocarbon cargo. The train is typically comprised of tanker cars that can be filled with raw heavy hydrocarbon, not dilbit thus allowing about 20% to about 30% additional heavy hydrocarbon to be transported in each tanker car. The system can keep the heavy hydrocarbon at a first, lower temperature en route and increase temperature to a second higher temperature as the train nears its terminus so that the tanker cars can be quickly emptied of their contents at the receiving terminal without the need to heat the tanker cars at the unloading terminal. The method disclosed herein for heating tanker cars in transit is to utilize waste heat from the locomotive diesel or gas turbine engines which is otherwise exhausted to the atmosphere.

SYSTEM AND METHOD FOR REDUCING VAPOR GENERATION IN LIQUEFIED NATURAL GAS FUELED VEHICLE
A method of reducing vapor generation in an LNG fueled vehicle is provided. The LNG fueled vehicle includes an LNG fuel system including an external LNG pump. The method includes a step of predicting if the LNG fueled vehicle will be operated during a first forthcoming time period using a controller. If the LNG fueled vehicle will be operated during the first forthcoming time period, as determined by the first predicting step, the method includes cooling the external LNG pump.
Locomotive natural gas storage and transfer system
An enclosure for containing cylinders includes an upper surface, a lower surface, opposing side walls spanning the upper and lower surfaces, and an end surface spanning the upper and lower surfaces, the upper surface, lower surface, side walls, and end surface defining an enclosed space. A plurality of inner walls divides the enclosed space to define bays. A removable door panel is opposite the end surface and includes dividers defining portions of the door panel corresponding to the bays. The enclosure includes a plurality of first contact pads, a plurality of first mounting plates, a plurality of second contact pads, and a plurality of second mounting plates. At least one first contact pad and at least one second contact pad is positioned in a corner of each bay and each portion, respectively, at an angle that is neither parallel or perpendicular to either the side walls or the upper surface.
Locomotive and transit system efficiency and emissions improvements
A system includes a prime engine connected to a prime engine exhaust stack that receives prime engine exhaust, a mixing duct section connected to the prime engine exhaust stack, a head-end power (HEP) generator connected to an HEP generator exhaust pipe that receives HEP generator exhaust, a single urea injector, and a selective catalytic reduction (SCR) system. The HEP generator exhaust pipe is connected to the mixing duct section, and the single urea injector injects urea into the HEP generator exhaust pipe upstream of the mixing duct section. The HEP generator exhaust and prime engine exhaust merge in the mixing duct section to form a merged exhaust that is received by the SCR system.
