THE "FLIP TOP" LID

To prevent windage loss of lading, exclude moisture and avoid freezing problems, the 232 100-ton gondola cars used to haul low-sulfur lignite in unit trains from a North Dakota mine to a South Dakota power plant have covers which are opened automatically at the loading site and swing clear when the car goes through a rotary dumper for unloading. The five-section roof has each segment fitted with a vertical post on which is a horizontal roller above the clearance line of the train's locomotive and caboose. This roller contacts a scroll above the track which is contoured to open and then close the lids. Features of the train and its operation are discussed.
