A system to transport and unload bulk materials includes at least one rail car and a moving wall system. The moving wall system has a first end, a second end, and a trough. The trough is configured to contain a payload of the at least one rail car. The trough includes sidewalls that contact the payload when loaded and move with the payload to move the payload towards the second end. The trough may be formed of at least one conveyor belt that forms a hopper of the at least one rail car. The trough may span a plurality of rail cars. The system may include a take-up system connecting the sidewalls. Each of the rail cars may include a frame and a plurality of pulleys connected to the frame may support the trough.
