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 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.
