Description
- The present disclosure relates generally to walkway systems for locomotives. More specifically, the present disclosure relates to a walkway system for adaptation to a pre-existing base structure of a locomotive car body that routes electrical wires associated with the locomotive.
- Locomotives are commonly known to employ a number of electrical units that are inter-connected via electrical wires and linings. Such electrical units may include, but are not limited to, electric fans, battery units, data acquisition systems, air compressors, and fluid pumps. Some of these electrical units are installed towards the frontal end of a locomotive car body, while some electrical units are installed towards the rear end of the locomotive car body. Generally, the electrical wires extend at least partially along the length of the locomotive car body, to establish an electrical connection between the electrical units at the frontal end and the electrical units at the rear end. Such electrical wires are routed through different portions of the locomotive car body to provide uninterrupted operations of the electrical units.
- Conventionally, wire routing mounts are installed on the locomotive car body, to route the electrical wires. Such wire routing mounts are generally mounted over a floor of the locomotive car body. However, by routing the electrical wires through the wire routing mounts mounted on the floor, considerable space on the floor needs to be dedicated to the passage of the electrical wires. Accordingly, a substantial degree of floor space remains ineffectively utilized. Moreover, as conventional wire routing mounts are generally installed on the floor of the locomotive car body, it may be cumbersome for an operator to access the electrical wires at time of service. This is because the floor may accommodate additional units and devices, which may need to be shifted and toggled to provide access to the electrical wires. Similarly, it is well known to route the electrical wires through others structures of the locomotive car body. However, it remains pertinent to deploy such electrical wiring in a space efficient manner.
- United States Patent Application 20120102846 is directed towards an appliance mount for a rail vehicle. The appliance mount is installed along a roof portion of the rail vehicle and is adapted to route the electrical components (or electrical wires). However, the appliance mount for the locomotive car body causes space utilization issues, as the roof of a locomotive car body commonly accommodates a number of auxiliary units that are required for varied applications of the locomotive car body. In such arrangements, during service of the locomotive, it may still be cumbersome for the operator to access the appliance mount.
- Various aspects of the present disclosure illustrate a walkway system for adaptation to a pre-existing base structure of a locomotive car body. The walkway system includes a first side panel, a second side panel, a base section, and a cover panel. The base section is structured and arranged to overlay the pre-existing base structure of the locomotive car body. The base section is connected to the first side panel and the second side panel. The first side panel, the second side panel, and the base section define at least one passageway. The cover panel is structured and arranged to removably engage with the first side panel and the second side panel. The passageway is enclosed by the cover panel when the cover panel is engaged with the first side panel and the second side panel. Moreover, the passageway is accessible when the cover panel is selectively removed.

FIG. 5 is a rear view of a second embodiment of the walkway system ofFIG. 2 . - Referring to
FIG. 1 , there is shown anexemplary locomotive 10. Thelocomotive 10 generally includes amain frame 12, alocomotive car body 14, atraction motor compartment 16, apre-existing base structure 18, and awalkway system 20. Thelocomotive car body 14 has a closed compartment structure, which is structured and arranged on themain frame 12. Thelocomotive car body 14 extends longitudinally between afrontal end 22 and arear end 24 of themain frame 12. Thelocomotive car body 14 includes a firstelectrical unit 26 and a secondelectrical unit 28. The firstelectrical unit 26 may be a high voltage cabinet, defined proximal to thefrontal end 22 of themain frame 12. The secondelectrical unit 28 may be an electrical appliances cabinet, defined proximal to therear end 24 of themain frame 12. The firstelectrical unit 26 and the secondelectrical unit 28 are generally electrically connected via electrical wires 30 (FIG. 2 ) that extend along a length, L of thelocomotive 10, to facilitate the electrical connection. - The
pre-existing base structure 18 is a flat platform mounted on themain frame 12 of thelocomotive 10, adjacent to afirst side 32 of thelocomotive car body 14. Thepre-existing base structure 18 provides a mounting base for thewalkway system 20. Thewalkway system 20 is mounted on thepre-existing base structure 18 and is defined adjacent to thefirst side 32 of thelocomotive car body 14. Thewalkway system 20 includes aplatform 34, which facilitates an operator to stand on theplatform 34 and move from one portion of thelocomotive 10 to another portion of thelocomotive 10. - Referring to
FIG. 2 , there is shown an exemplary rear view of thelocomotive 10 ofFIG. 1 , along the section A-A′. Thewalkway system 20 of thelocomotive car body 14 is also shown. Thewalkway system 20 may be a rectangular shaped structure that facilitates routing of theelectrical wires 30 that electrically connects the firstelectrical unit 26 and the secondelectrical unit 28. Theelectrical wires 30 extend along the length, L, of thelocomotive 10 and are routed through thewalkway system 20. Although, the present disclosure contemplates thepre-existing base structure 18 and thewalkway system 20 structured on thefirst side 32 of thelocomotive car body 14, an auxiliarypre-existing base structure 36 and anauxiliary walkway system 38 is structured on thesecond side 40, as well. In an embodiment, theauxiliary walkway system 38 is adapted to facilitate ducting of cooling air to the traction motor compartment 16 (FIG. 1 ) of thelocomotive 10. Although, the present disclosure contemplates routing and management ofelectrical wires 30 through thewalkway system 20, it may also happen that thewalkway system 20 is being utilized to route and manage fluid conduits or similar such components. - Referring to
FIG. 3 , a cross-sectional view of thewalkway system 20 is shown. For ease in understanding and clarity purposes, routing and arrangement of a singularelectrical wire 30 through thewalkway system 20 is depicted. Similar routing and arrangement of multiple otherelectrical wires 30 through thewalkway system 20, may also be contemplated. As illustrated, thewalkway system 20 has a rectangular cross-section, which is uniformly structured along the length, L, or an expanse of thewalkway system 20. However, a cross-section of thewalkway system 20 may vary and may depend on multiple factors, such as a position or shape of thepre-existing base structure 18 and a position of the first electrical unit 26 (FIG. 1 ) and the secondelectrical unit 28. Accordingly, this aspect need not be seen as limiting in any way. Thewalkway system 20 includes abase section 42, afirst side panel 44, asecond side panel 46, and acover panel 48. - The
base section 42 is structured and arranged to overlay thepre-existing base structure 18. Thebase section 42 includes afirst side portion 50 and asecond side portion 52. Thefirst side panel 44 is attached to thefirst side portion 50 of thebase section 42 and extends in a vertical direction relative to thebase section 42. Thefirst side panel 44 includes aconnection port 54, adjacent to the secondelectrical unit 28 of thelocomotive car body 14. Similarly, an auxiliary connection port (not shown) adjacent to the firstelectrical unit 26, may also be provided. Thesecond side panel 46 is attached to thesecond side portion 52 of thebase section 42 and extends in a vertical direction relative to thebase section 42. At least onepassageway 56 is defined between thebase section 42, thefirst side panel 44, and thesecond side panel 46, of thewalkway system 20. In deployment, theelectrical wire 30 is positioned and routed through thepassageway 56 of thewalkway system 20. Notably, one end of theelectrical wires 30 pass through theconnection port 54, to electrically connect to the secondelectrical unit 28. Similarly, another end of theelectrical wire 30 pass through the auxiliary connection port (not shown), to electrically connect to the firstelectrical unit 26. However, similar to a routing of theelectrical wire 30, multiple wires can be routed through theconnection port 54. - The
cover panel 48 is removably engages with each of thefirst side panel 44 and thesecond side panel 46. Although the present disclosure contemplates slidable engagement of thecover panel 48 with thefirst side panel 44 and thesecond side panel 46, various other engagements, may also be contemplated. Thecover panel 48 defines theplatform 34 that facilitates the operator to stand and traverse on thewalkway system 20, allowing operator movement from thefrontal end 22 to therear end 24. In a deployed state, as shown inFIG. 3 , thecover panel 48 engages with each of thefirst side panel 44 and thesecond side panel 46. In so doing, thecover panel 48 encloses thepassageway 56. A removal of thecover panel 48 facilitates an access to theelectrical wires 30. - Referring to
FIG. 4 , there is shown thewalkway system 20 ofFIG. 3 with thecover panel 48 partially removed from thewalkway system 20. When thecover panel 48 is removed from thewalkway system 20, thepassageway 56 of thewalkway system 20 is exposed to external environments. This facilitates the operator to access theelectrical wire 30 positioned and routed within thewalkway system 20. - Referring to
FIG. 5 , there is shown an alternate embodiment of awalkway system 20′ of the locomotive 10. Thewalkway system 20′ includes one or morevertical divisions 58, which are attached to thebase section 42 of thewalkway system 20′. In this embodiment, thewalkway system 20′ includes twovertical divisions 58 attached to thebase section 42. Therefore, thewalkway system 20 defines threepassageways walkway system 20′. Each of the threepassageways first passageway 60, may route a 6-wattelectrical wire 30, as shown inFIG. 5 . - During operation, the locomotive 10 employs the
walkway system walkway system walkway system frontal end 22 to therear end 24, and vice versa. Second, thewalkway system electrical wires 30, to enable an electrical connection between the firstelectrical unit 26 and the secondelectrical unit 28. - In application, the
electrical wires 30 are prewired in thepassageways walkway system electrical unit 26 and the secondelectrical unit 28. More particularly, one end of theelectrical wires 30 may pass through the auxiliary connection port (not shown) of thewalkway system electrical unit 26, while the another end of theelectrical wires 30 exits through theconnection port 54 to connect with the secondelectrical unit 28. As thewalkway system locomotive car body 14 is considerably efficiently utilized. - Furthermore, during service and repair of the locomotive 10, access to the
electrical wires 30 may be required. In such a situation, an operator slideably removes thecover panel 48 of thewalkway system passageways electrical wires 30. Such an access to theelectrical wires 30 is relatively easier compared to when theelectrical wires 30 are laid through a floor or a roof of the locomotive 10. Therefore, theelectrical wires 30 may be serviced or replaced without the need to physically enter the locomotive 10 or disassemble any pre-existing units. Moreover, such a provision facilitates an operator to service the locomotive 10, from an external environment of the locomotive 10, thus reducing service cost and effort. - It should be understood that the above description is intended for illustrative purposes only and is not intended to limit the scope of the present disclosure in any way. Thus, one of ordinary skill in the art will appreciate that other aspects of the disclosure may be obtained from a study of the drawings, the disclosure, and the appended claim.
