Description
- Gondola railcars and other open-topped railcars carrying railroad ties, ballast, and other rail track materials are loaded and unloaded via excavators, tie cranes, and other material moving machines. Most excavators climb directly on top of the rail track materials to traverse and unload the railcars. This can be unstable and limits excavator mobility once some of the rail track materials have been removed. Excavators also often have to rearrange rail track materials on the next railcar before advancing onto the next railcar.
- Some material moving machines use temporary scaffolding positioned on top of the railcars, but the temporary scaffolding has to be moved repeatedly. Other material moving machines have specialized bases or wheels that allow them to traverse top sidewall edges of a series of connected railcars, but the specialized bases are cumbersome and inefficient, and the specialized wheels require connector rails to be installed between railcars. Furthermore, material moving machines generally must be transported between work zones via non-rail means.

forward sidewall 24 extends vertically from thefloor 18 between theleft sidewall 20 and theright sidewall 22 near a forward end of therailcar 10. Theforward sidewall 24 may include an upper edge, below which thepayload 104 may be ensured to be retained in thepayload bay 34. - The
rear sidewall 26 may be substantially similar to theforward sidewall 24. That is, the rear sidewall extends vertically from thefloor 18 between theleft sidewall 20 and theright sidewall 22 near a rearward end of therailcar 10. Therear sidewall 26 may include an upper edge similar to the upper edge of theforward sidewall 24. - The
reinforcement ribs 28 extend vertically and horizontally along theleft sidewall 20,right sidewall 22,forward sidewall 24, andrear sidewall 26 to improve their strength. Thereinforcement ribs 28 may include I-beams, C-beams, box beams, or the like. - The left track 30 (best seen in
FIGS. 1 and 3 ) is positioned near theleft sidewall 20 in thepayload bay 34 and may include a plurality ofpedestals 36, a plurality ofreinforcement legs 38, and a plurality oframps 40. Alternatively, theleft track 30 may be a single un-broken ledge. Theleft track 30 may be spaced above thefloor 18 and may also be spaced below the upper edge of theleft sidewall 20. - The
pedestals 36 are spaced apart from each other and each include anupper surface 42. In one embodiment, theupper surface 42 is vertically approximately halfway between thefloor 18 and the upper edge of theleft sidewall 20. Some of thepedestals 36 adjacent to each other may be laterally bridged to provide unmitigated support points as theexcavator 100 transitions from theramps 40 to thepedestals 36. In one embodiment, thepedestals 36 are positioned straight across from corresponding pedestals of theright track 32. Alternatively, thepedestals 36 may be staggered relative to pedestals of theright track 32. - The
reinforcement legs 38 extend vertically along theleft sidewall 20 to thepedestals 36. Thereinforcement legs 38 distribute weight of theexcavator 100 down to theframe 16. Thereinforcement legs 38 may also be integrated with some of thereinforcement ribs 28. - The
ramps 40 extend diagonally upward from thepedestals 36 to the upper edges of theforward sidewall 24 and therear sidewall 26. Theramps 40 may includegrips 44 for engaging tracks (or wheels, tires, etc.) of theexcavator 100. Theramps 40 allow theexcavator 100 to descend onto thepedestals 36 from and climb back over the upper edges of theforward sidewall 24 andrear sidewall 26. In this way, therailcar 10 is independent from theexcavator 100 and vice versa, and theexcavator 100 can traverse between adjacent railcars and move between therailcar 10 and an excavator transport vehicle. - The right track 32 (best seen in
FIG. 2 ) is positioned near theright sidewall 22 opposite theleft track 30 in thepayload bay 34 and is substantially similar to theleft track 30. That is, theright track 32 may include a plurality ofpedestals 46, a plurality ofreinforcement legs 48, and a plurality oframps 50. Alternatively, theright track 32 may be a single un-broken ledge. Theright track 32 may be spaced above thefloor 18 and may also be spaced below the upper edge of theright sidewall 22. - The
pedestals 46 are spaced apart from each other and each include anupper surface 52. In one embodiment, theupper surface 52 is vertically approximately halfway between thefloor 18 and the upper edge of theright sidewall 22. Some of thepedestals 46 adjacent to each other may be laterally bridged to provide unmitigated support points as theexcavator 100 transitions from theramps 50 to thepedestals 46. In one embodiment, thepedestals 46 are positioned straight across from correspondingpedestals 36 of theleft track 30. Alternatively, thepedestals 46 may be staggered relative topedestals 36 of theleft track 30. - The
reinforcement legs 48 extend vertically along theright sidewall 22 to thepedestals 46. Thereinforcement legs 48 distribute weight of theexcavator 100 down to theframe 16. Thereinforcement legs 48 may also be integrated with some of thereinforcement ribs 28. - The
ramps 50 extend diagonally upward from thepedestals 46 to the upper edges of theforward sidewall 24 and therear sidewall 26. Theramps 50 may includegrips 54 for engaging tracks (or wheels, tires, etc.) of theexcavator 100. Theramps 50 allow theexcavator 100 to descend onto thepedestals 46 from and climb back over the upper edges of theforward sidewall 24 andrear sidewall 26. - The
left track 30 andright track 32 may be positioned for 102-inch span excavator tracks to accommodate excavators that can be transported via truck to any location without special permits. Therailcar 10 may fall within Plate F AAR railcar guidelines. An overall height of therailcar 10 and vertical position of theleft track 30 andright track 32 may ensure an overall height of therailcar 10 plus excavator to not exceed 17 feet. Therailcar 10 may be connected with similar railcars to form a train of railcars that theexcavator 100 may traverse and unload. - The above-described
railcar 10 provides several advantages. For example, theleft track 30 andright track 32 elevate theexcavator 100 above thefloor 18 and retain theexcavator 100 below upper edges of theleft sidewall 20 andright sidewall 22. This allows theexcavator 100 to remove material(s) from thepayload bay 34 without needing to be on thefloor 18 and without being relegated to a position completely above the upper edges of theleft sidewall 20 andright sidewall 22. This is more effective and safer for the excavator operator. Thepedestals excavator 100 while allowing for maximum payload space between thepedestals ramps railcar 10 from an excavator transport vehicle. - The description and drawings are illustrative and are not to be construed as limiting.
