Embodiment Construction

[0021]With reference to FIGS. 1 and 2, an axle-mounted braking regeneration energy storage and acceleration system 100 for a passive rail car 110 will be described. As used herein, “passive rail car” refers to rail car primarily propelled (e.g., pulled, pushed) by a separate driving rail car (e.g., locomotive). A passive rail car has no primary power unit for the conversion of chemical fuel into electric or kinetic energy used to propel the vehicle. A rail car is defined as a flange wheeled vehicle where the wheels roll on and are guided by rails on a road bed also known as a railroad track. Although the braking regeneration system 100 will be described as being axle-mounted, in alternative embodiments, the braking regeneration system 100 is mounted to other and / or additional structures of a passive rail car.

[0022]In the embodiment shown, the passive rail car 110 is a Comet V commuter rail car including multiple axles 120 with wheels 130 on opposite ends of the axles 120 and a frict...

Abstract

A method of using one or more electric locomotive and energy storage car combinations to assist a train consist up an uphill climb, the one or more electric locomotive and energy storage car combinations each having one or more diesel electric locomotives and one or more separate energy storage cars, including adding the one or more electric locomotive and energy storage car combinations to the train consist prior to an uphill climb; using the one or more electric locomotive and energy storage car combinations to assist the train consist up the uphill climb; and removing the one or more electric locomotive and energy storage car combinations from the train consist after the uphill climb. The one or more electric locomotive and energy storage car combinations are added to a train consist traveling downhill to assist with the downhill slowing through dynamic braking regeneration that is used to recharge the energy storage of the one or more separate energy storage cars.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation-in-part application of U.S. patent application Ser. No. 11 / 420,064, filed May 24, 2006. This application claims the benefit of this prior application and this prior application is incorporated by reference herein as though set forth in full.FIELD OF THE INVENTION[0002]The field of the invention relates to locomotive assists to assist the propulsion of freight trains up long grades.BACKGROUND OF INVENTION[0003]Railroad operations often use one or more additional diesel locomotives to assist the propulsion of freight trains up long grades. At the top of the grades the locomotives are uncoupled from the train at a switch yard or siding and sent back to the bottom of the grade to assist additional trains requiring assistance up the long grades.[0004]A problem with these diesel locomotives used to assist the propulsion of freight trains up long grades is that the diesel locomotives consume a lot of diesel fuel...
