A railway wagon for semitrailers and the like has a first bogie, a second bogie and a carrying section therebetween. An elongated channel configured to receive conduits for air, hydraulics and/or electronics extends between the two bogies. The media channel is lowered in a mechanical way when the carrying section is turned out to a loading/unloading position.

A system for transporting vehicles includes a railcar, a deck, a fastener, a screw, and a travelling nut. The deck is positioned within the railcar and is for supporting a plurality of vehicles. The fastener is coupled to the deck and operable to couple the deck to a wall of the railcar. The fastener prevents a vertical position of the deck within the railcar to be adjusted when the deck is coupled to the wall by the fastener. The screw is coupled to the railcar and the travelling nut is operably coupled to the screw. The travelling nut is operable to adjust a vertical position of the deck within the railcar as a position of the travelling nut on the screw changes when the screw is turned.

A system includes a railcar, a first side screen, a second side screen, and an adjustment system. The railcar includes a roof section. The first side screen is coupled to a side of the railcar. The second side screen is coupled to the side of the railcar. The second side screen overlaps a portion of the first side screen. The adjustment system is coupled to the railcar and is operable to adjust a vertical position of the roof section.

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.

There is provided a method of adjusting a height of a car floor plane of a railroad car relative to a platform of a train station. The method includes, using a height adjusting system mounted to an exterior side of the railroad car adjacent the car floor plane, emitting a first ultrasonic beam towards the platform of the train station and monitoring a reflection of the first ultrasonic beam; and generating a first signal based on said monitoring the reflection of the first ultrasonic beam. The method includes, using a processor, operating an actuator of a suspension system of the railroad car to adjust the height of the car floor plane to a height of the platform of the train station based on the generated first signal.

A modular railcar includes a modular top system that is configured to hold one or more coils of material, and a railcar underframe that supports the modular top system. The modular top system includes a pair of side sills and one or more troughs disposed between the pair of side sills. Each side sill of the pair of side sills extends a longitudinal length of the modular top system. Each trough of the one or more troughs is configured to hold a coil of the one or more coils of material. The underframe includes one or more coupling apparatuses that are configured to detachably engage the modular top system when the modular top system is positioned on top of the underframe.

A vehicle may include a frame structure, four wheels, and four independent suspension systems coupled to the frame structure and configured to support the wheels relative to the frame structure. Each suspension system may include a suspension arm movably coupling a respective wheel to the frame structure, a torsion bar coupled to the suspension arm and imparting a spring force on the suspension arm, a preload arm coupled to the torsion bar, and a preload adjustment motor coupled to the preload arm and configured to rotate the torsion bar to adjust a preload on the torsion bar.
