DETAILED DESCRIPTION

(14) Embodiments disclosed herein include a modular autorack lighting track 200 having multiple elongated track segments 400, and a method for upgrading an autorack railcar by attaching such lighting tracks 200 to the floor(s) of the deck(s) of an autorack. The lighting track preferably provides adequate lighting for employees to work (such as at least 1 foot candle of light) at the areas where wheel chocks are installed and removed. It provides lighting for vehicle inspection and is non-intrusive for loading/unloading personnel. It is preferably low voltage (e.g. 24V) within the vehicle bodies.

(15) FIG. 1 shows an example of prior art autorack loaded with cars.

(16) FIG. 2 is a rear view of a bi-level autorack 202 with upper and lower decks with an elongated lighting track 200 attached to the floor of each of the two decks. Vehicle trackways 201 on which vehicle tires rest are also shown.

(17) Each lighting track 200 preferably extends along the length, or a substantial portion, of the central longitudinal axis of one deck of the autorack as shown in FIGS. 2 and 3. As used herein, longitudinal axis refers to a notional line equidistant from the left and right sides of the autorack going from one end (front or rear) of the autorack to the other end of the autorack. For example, the lighting track 200a attached to the upper deck of the autorack as shown in FIG. 2 substantially extends along the full length of the longitudinal axis of the autorack. By extending along the length, or a substantial portion, of the central longitudinal axis of one deck of the autorack, it is not necessarily meant, and is not essential, that the light track be coincident with the longitudinal axis. For example it may be displaced to the left or right of the axis, although this is not preferred.

(18) The lighting track 200 is substantially parallel to straight portions of the railway tracks on which the autorack is positioned, and approximately equidistant from the left and right sides of the autorack. In this context, approximately equidistant means that the lighting track is always in the central portion of the deck floor, spaced apart from the vehicle trackways. The sides of the autorack refer to the left and right sides of the floors of the decks of the auto racks. The autorack may or may not have vertical physical walls corresponding to each side of the autorack.

(19) The lighting track 200 preferably is formed from multiple elongated track segments 400 placed end to end and attached to the deck floor to form the lighting track 200. FIG. 4 shows a single track segment 400 in isolation and FIG. 5 shows an exploded view of the same track segment 400. Each track segment 400 includes a base track 401 that is an elongated rigid piece configured to receive an elongated lighting device 402, which is positioned in the central portion of the base track 401, and shown in an exploded view in FIG. 6. The base track 401 is preferably made of metal which is typically galvanized steel, e.g. 22 gauge, but other material may be used, as would be recognized by skilled persons. The lighting device 402 is covered by a translucent cover 403, which may be transparent, that acts as a light-transmitting window that is preferably made of polycarbonate material, but other translucent/transparent materials may be used. The term translucent as used herein includes transparent. The cover 403 is adhesively attached to the base track 401 via flanges 801, as shown in FIG. 8, the flanges extending laterally a short distance from the lower ends of the cover 403 towards the sides of the autorack. The cover 403 is preferably resistant to ultraviolet radiation, impacts, crush, abrasions, water, oil and chemicals.

(20) Each track segment 400 preferably has front and rear caps 404a, 404b attached to the front and rear ends of the track segment 400 respectively. Each cap 404 has openings 406 though which electrical wires connected to the power bus of the track segment 400 extend to facilitate electrical connection to other track segments adjacent to the front and rear of the track segment 400. Such power facilitates illumination of the lights in each lighting device 402.

(21) A track segment's base track 401 has a flat lower surface and is configured to be attached to a deck floor of an autorack parallel to the longitudinal axis of the autorack by welding using fasteners, such as rivets such as Holden deck rivets p/n GLC 2002 or Trinity p/n 164-38344-15, that extend through multiple openings 405 in the flat bottomed left and right sides of the base track 401. Other methods of attachment are also possible, such as welding the base track to the deck floor. Multiple track segments 400 are positioned end-to-end parallel to straight portions of the railway tracks and parallel to the longitudinal axis of the autorack along the floor of each deck of the autorack so that the track segments form an elongated lighting track 200. It is preferred that the lighting track 200 substantially extends along the length of the longitudinal axis of the deck, although this is not essential as long as the lighting track extends along a sufficiently long portion of the longitudinal axis of the deck so that it provides sufficient light to support chocking and de-choking of all the tires of vehicles when the deck is fully loaded with vehicles.

(22) FIG. 6 is an exploded view of the lighting device 402 of FIGS. 4 and 5. The lighting device 402 comprises a galvanized steel track 604, in which high amperage LED strips 602 are placed, the LED strips 602 being electrically connected by copper connectors 603. The LED strips 602 are covered by a polycarbonate protective lens 601. Watertight Silicone end caps 605 are attached to each end of the lighting device 402.

(23) FIG. 7 shows the lighting device of 402 FIG. 4 in isolation sowing the LED board 701 with attached LEDs 702 and electric connectors 703 for electrically connecting the power busses of adjacent track segments 400 by wires, such as 12 AWG wire, extending though the openings 406 in the end caps 404. FIG. 10 shows the electrical connection 1000 between two adjacent track segments.

(24) Adjacent track segments 400 are secured together and to the deck floor by track connectors 1101, 1102 and 1103 as shown in FIGS. 11A, 11B and 11C. The track connectors cover and protect the electrical wires connecting the segments 400 and have openings that align with openings 405 in the segments 400 so that the connectors and ends of the segments 400 can be securely attached to the deck floor, for example by rivets.

(25) Track segments 400 may vary in length, such as 23, 45.5, 58 and 105.5, so that the optimal lighting track length can be achieved. The LED strips may be 22.5 or 35 long.

(26) FIG. 11A shows a straight track connector 1101 for connecting two segments 400 that are secured the deck floor. FIGS. 11B and 11C should connectors 1102, 1003 where the segments 400 meet at an angle, for example 4.75 in FIG. 11B and 175.25 in FIG. 11C.

(27) For each terminal track segment, one end (the terminal end) of which is not adjacent to another track segment, the terminal end is preferably covered by a terminal track connector 1300 as shown in FIG. 13 that is attached to the deck floor.

(28) The lighting device 402 of each track segment 400 has multiple lights, preferably light-emitting diodes (LEDs), and a printed circuit board (PCB) 701 with an integrated power bus. The power bus of a lighting device is connected to a power source configured to light the plurality of lights in the lighting device.

(29) Preferably, the ends of the lighting track on the lowest level (the A deck) are terminated by a steel tongue 202 that splits the lighting track to facilitate viewing the chocking areas on both sides of the tongue by connecting one terminal segment 400 to each side of the tongue 202.
