ABSTRACT:
A railway tank car is provided for interconnection in fluid communication with associated tank cars. Each of the tank cars includes a tank mounted on a chassis structure with two lading conduits respectively coupled to the tank, each having an outer end extending outwardly from the tank adjacent to the top thereof and at least one having an inner end extending into the tank and terminating near the bottom thereof. A vapor vent is connected to the tank to vent gas vapors produced during loading. The vent is closed by a valve actuated by a control mechanism in response to a level sensing means which determines the level of liquid lading in the tank. The tank car or train may be loaded or unloaded from either end thereof since the cars can have symmetrical internal piping, and, similarly the gas vapor may be collected from either end of the tank car or train.
