Abstract: A railroad hopper car having a single cargo-receiving hopper extending over substantially the length of a car body having a cargo discharge portion occupying most of the available distance between the wheeled trucks supporting opposite ends of the car body. The car has no pair of slope sheets separating longitudinally-adjacent hoppers and defining unusable space beneath the slope sheets, and so the overall length of such a hopper car capable of carrying a desired volume of cargo can be less than that of one with multiple separate hoppers. Cargo discharge openings are arrayed along the length of the cargo discharge portion, and a unitary multi-gate assembly is supported within the cargo discharge portion of the car body so as to be movable longitudinally of the car body to open or close all of the cargo discharge openings simultaneously.

Abstract: A system includes a railcar, a first deck, and a second deck. The second deck is positioned within the railcar above the first deck. The second deck includes a first portion, a second portion coupled to a first end of the first portion, and a third portion coupled to a second end of the first portion opposite the first end. The second and third portions can move towards a center of the first portion such that the first portion is positioned above or beneath the second and third portions.

Abstract: According to some embodiments, a railcar comprises a hopper with a sloped sheet and a discharge door. A first end of the discharge door is coupled to the railcar and pivots the discharge door between closed and open positions. The sloped sheet comprises a discharge end that is in contact with the discharge door when in the closed position. A second end of the discharge door extends beyond the discharge end of the sloped sheet when in the closed position. The discharge door comprises a lip disposed at its second end that extends generally perpendicular to the discharge door and parallel to the sloped sheet when the discharge door is in the closed position. The sloped sheet comprises a gasket coupled to its exterior portion. The lip of the discharge door contacts the gasket when in the closed position.

Abstract: A railcar security system that includes a railcar, a first sensor having a first sensor type and a first sensor location with respect to the railcar, a second sensor having a second sensor type and a second sensor location with respect to the railcar, a first lighting group linked with the first sensor, a second lighting group linked with the second sensor, and a controller. The controller is configured to receive an arming signal, receive a trigger signal indicating a sensor of the plurality of sensors has been triggered, determine a sensor type and a sensor location for the sensor based on the trigger signal, activate the first lighting group when the determined sensor type and the determined sensor location correspond with the first sensor, and activate the second lighting group when the determined sensor type and the determined sensor location correspond with the second sensor.
