Abstract: A mobile air cleaner for removing particulate materials from a chamber of a railcar or container is mounted on a motor truck operable to locate the air cleaner adjacent a railcar. The cleaner has an air hose connected to a motor driven fan for moving air through the hose and into the chamber of the railcar to move particulate material into a box located below the railcar. A lift device mounted on the truck has articulated booms and a work person carrier that can be located in the chamber of the railcar allowing the work person to move the hose adjacent the particulate material in the chamber and visually observe the cleaning operation.

Abstract: A motor truck has a frame supporting an enclosed housing having two compartments accommodating a fuel tank, an oil tank in one compartment and a container for sand in the other compartment for servicing a rail locomotive located at a remote location or rail yard. Pumps mounted located in the one compartment move the fuel, oil, and water from the tanks through hoses to tanks on the locomotive. Air flowing from an air compressor moves sand from the sand container into a sand hopper on the locomotive.

Abstract: A mobile vacuum cleaner for removing particulate materials from a chamber of a railcar or container is mounted on a motor truck operable to locate the vacuum cleaner adjacent a railcar. The cleaner has a material pick-up hose connected to a box and a motor driven fan for drawing air through the hose and box to pick up particulate materials from the chamber of the railcar and transport the particulate materials to the box. A lift device mounted on the truck has articulated booms and a work person carrier that can be located in the chamber of the railcar allowing the work person to move the hose adjacent the particulate material in the chamber and visually observe the cleaning operation.

Abstract: A motor truck has a frame supporting a fuel tank, an oil tank and a water tank along with a container for sand for servicing a rail locomotive located at a remote location or rail yard. Pumps mounted on the frame move the fuel, oil, and water from the tanks through hoses to tanks on the locomotive. A hoist on the truck moves the sand container from the truck to a location adjacent the locomotive to allow sand to flow into a sand hopper on the locomotive.

Abstract: An open top railroad car is equipped with end caps that allow air to flow into and out of the car chamber. A tarp extended between the end caps covers the open top of the car. A roll tube is secured to one longitudinal side of the tarp. A manually operated crank attached to the roll bar with a flexible cord is used by a yardperson to selectively roll the tarp to it's open and closed positions. A plurality of straps joined to the roll tube are connected to winches operable to hold the tarp in it's closed position.

Abstract: A conveyor coupled to a skid motor vehicle operates to unload bulk granular material from a railroad hopper car. The conveyor has an obtuse configured frame supporting an endless belt extended about an idler roller and a driven roller. A hydraulic motor mounted on the frame supplied with hydraulic fluid under pressure from the hydraulic system of the motor vehicle rotates the drive roller thereby moving the belt relative to the frame and mount thereon. A pair of transverse tubular box members are secured to the bottom of the frame to accommodate forks attached to the skid motor vehicle whereby the skid motor vehicle can lift the conveyor and transport it to another location.
