RAILROAD TANK CAR ABSTRACT Disclosed is a container for a plurality of non-compatible liquids, the container comprising a generally cylindrical tank having a generally horizontal longitudinal axis. A flexible diaphragm is in the tank, the periphery of the diaphragm contacting the wall of the tank in a generally vertical plane which generally bisects the tank. The diaphragm alternately lies against opposite portions of the tank so as to define different chambers for such non-compatible liquids. Means are provided for sealing the diaphragm against the wall, and means are provided for filling the chambers with liquid. The means for filing the chambers comprise a pair of liquid inlet conduits extending upwardly from the upper portion of the tank, the inlet conduits being located on opposite sides of the plane. Each inlet conduit communicates with a chamber inside of the tank on a different side of the diaphragm. A movable lid closes each of the inlet conduits and means are provided for automatically venting both of the conduits to the atmosphere whenever either of the conduits is opened, whereby the chambers on both sides of the diaphragm are vented to the atmosphere whenever either chamber is filled with liquid.
