Embodiment Construction

[0013] This paper presents unique equipment and methods for use in combined ship-rail-road freight systems. Some of the apparatus that can be used to perform the methods described herein was previously described in US Pat. US Patent Application No. 15 / 144,517, entitled "Method and Apparatus for Intermodal Container Handling," the disclosures of each of which are incorporated herein by reference in their entirety. The description provided in this disclosure refers to embodiments that use the design of the tractor most commonly used in road transportation applications in North America, namely, tractors used to pull semi-trailers. By definition, a semi-trailer is a trailer that does not have a front axle. In a semi-trailer, most of the weight of the semi-trailer is supported by the road tractor. Road tractors are often equipped with large diesel engines, and transmission improvements can be used to provide sufficient power for short-train rail operations.

Abstract

A method and apparatus for rail-to-road shipping. Apparatus for powering short trains, said apparatus comprising: a rail car, said rail car comprising a frame, said frame having a front, a rear, and a deck, said frame supported by a first bogie and by a second bogie, said first bogie having a first rail axle and a first pair of flanged main rail wheels, said first bogie located at or near the front of said frame, said second bogie having a second rail axle and a second pair of flanged main rail wheels, said second bogie located at or near the rear of said frame; a first gear system, said first gear system comprising a plurality of gears configured to receive motive power supplied from external rail driving gears; a first over-the-road tractor, said first over-the-road tractor comprising a first drive axle and first and second sets of dual wheels on opposing sides of said first drive axle; and first and second external rail driving gears, wherein said deck includes apertures therein to accommodate therethrough said first and second sets of dual wheels, so that when said first over-the-road tractor is placed on said deck, said first and second external rail driving gears are located in meshing engagement with said a first gear system for supply of motive power thereto from said first over-the-road tractor.

Description

technical field [0001] The present application relates to systems for providing transport of semi-trailers and trailers, including local rail transport followed by transfer to road for local truck transport, and to equipment that can be used to facilitate such transport and transfer. Background technique [0002] In the trucking industry, it is well known that in many cases, the last few miles become a source of delay and additional cost, as small quantities of freight may need to be transported, especially by rail, to remote locations. However, since transportation typically involves rail transiting road-capable trailers to a location close to their final destination, subsequent connection to trucks is quite labor-intensive and time-consuming. [0003] As a result, the use of rail-road intermodal systems and methods has been largely limited to long-distance freight. However, in an environment of increasingly competitive freight costs, there remains a need for improvements ...
