Abstract
A rubber tired railway plow (100) has a plow unit (102) mounted to a plate (111) which extends across the forward end of the rubber tired vehicle (100). The plow unit (102) is attached so as to be movable on the plate (111). Wedges (122, 123) are used to maintain the plow unit (102) in position on the plate (111). When the wedges (122, 123) are removed, the plow unit (102) is movable on the plate (111) from one side of the vehicle (100) to the opposite side thereby to be able to plow on either side of the rails (141).
Claims2
A rail mounted excavating unit on a first railcar for removing ballast and overburden from a railbed and a rail mounted storage vehicle for storing ballast and overburden, said rail mounted storage vehicle being on a second railcar for holding said ballast and overburden removed by said excavating unit, said rail mounted storage vehicle on said second railcar being connected to and moveable with said rail mounted excavating unit on said first railcar, said first and second railcars being connected through a hitch assembly, said rail mounted storage vehicle holding said removed ballast and overburden and allowing said removed ballast and overburden to be returned to said railbed, and further comprising a railway plow having a forward set of two pairs of rail wheels, each of said railwheels being rotatable about a railwheel axis, said two pairs of railwheels further being rotatable about a bogey axis located substantially symmetrically relative to said railwheel axes.
A rail mounted excavating unit on a first railcar for removing ballast and overburden from a railbed and a rail mounted storage vehicle for storing ballast and overburden, said rail mounted storage vehicle being on a second railcar for holding said ballast and overburden removed by said excavating unit, said rail mounted storage vehicle on said second railcar being connected to and moveable with said rail mounted excavating unit on said first railcar, said first and second railcars being connected through a hitch assembly, said rail mounted storage vehicle holding said removed ballast and overburden and allowing said removed ballast and overburden to be returned to said railbed, and further comprising a high rail positioned on a railway plow, said high rail comprising a pair of railwheels begin hydraulically rotatable about a bogy axis, and an accumulator maintained at a predetermined pressure, the accumulator substantially maintaining a predetermined contact force between said railwheels and track during operation of said railway plow on said track.
