Benefits of technology

[0030]The transversal genset according to the present invention offers a better HP/linear feet ratio compared to most actual locomotives with their gensets aligned along the length of the locomotive. The present genset also offers better access for maintenance purposes with full access

Problems solved by technology

Furthermore, refurbishment of gensets on locomotives of different lengths is complicated due to the fact that, when longitudinal or side-by-side configurations are used, the actual design and layout of the gensets needs to be adapted to each and every new platform length.
There is a lack of standardization in the major sub-assemblies of the locomotive which

Embodiment Construction

[0060]Referring to FIG. 4 for a schematic view and FIGS. 5-6 for exploded perspective views, the present invention provides a locomotive 30 comprising a platform deck 32 and a plurality of generator sets 34 on the platform deck 32, each generator set 34 occupying a space associated with a generally oblong footprint 36 on the platform deck 32, the footprint 36 defining a longitudinal axis along a longest length of the footprint 36. Each generator set 34 is positioned on the platform deck 32 such that the longitudinal axis of the corresponding footprint 36 is generally perpendicular to a direction of travel of the locomotive 30.

[0061]As explained previously, this layout of the generator sets on the platform has a number of advantages. A comparison of this transversal configuration of gensets with respect to prior art configurations is illustrated schematically in FIG. 4 and a summary comparison between the same three configurations is provided in the following table:

Abstract

A generator set has a transversal configuration on the locomotive. The generator set and its configuration on the platform offer good performance with respect to the space it occupies along the length of the locomotive platform deck, and offer better access for maintenance purposes. A walkway interface structure supports a modular design for locomotives using standardized major sub-assemblies that can be easily interfaced from one locomotive and under-frame to another.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims the benefit, under 35 U.S.C. §119(e), of U.S. Provisional Application 60 / 929,286 entitled “Transversal Generator Set and Modular Design for Refurbishment of Locomotives” to Burns et al filed Jun. 20, 2007, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention generally relates to the refurbishment of train locomotives, or the like. More particularly, it relates to a transversal modular generator set to be installed on a locomotive during its refurbishment. The present invention also relates to a modular design concept which facilitates the refurbishment of locomotives through the use of a walkway interface system and standardized locomotive major sub-assemblies.BACKGROUND OF THE INVENTION[0003]Refurbishment of locomotive generator sets is carried out often these days as a cost-effective way for replacing older locomotives that may otherwise have other highly functional su...
