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.

The invention provides an engineering vehicle having a ballast unloading device (100) and a ballast leveling device (200). The engineering vehicle includes a vehicle body (10), and the ballast unloading device (100) and the ballast leveling device (200) arranged on the vehicle body (10). The ballast unloading device (100) includes: a ballast carrying portion (20) provided with ballast unloading openings (21), and the ballast carrying portion (20) being arranged on the vehicle body (10); ballast unloading doors (30) capable of rotating relative to the ballast carrying portion (20), inner unloading passages (31) and outer unloading passages (32) being arranged on the ballast unloading doors (30), the ballast unloading doors (30) further including stop portions (33) located between the inner unloading passages (31) and the outer unloading passages (32). The ballast leveling device (200) includes: a plough piece (220) slidably fixed to the vehicle body (10) so as to ascend or descend relative to the vehicle body (10), and a plough head (224) used for leveling ballasts being arranged on the plough piece (220); a first crank (230) rotationally fixed to the vehicle body (10); a connecting rod (240), with one end being rotationally connected with the first crank (230), and the other end being rotationally connected with the plough piece (220); and a driving part (250) used for driving the first crank (230) to rotate.
