ABSTRACT:
The tank of a railway tank car has two top-mounted lading conduits coupled thereto in fluid communication therewith. One of the lading conduits has the inner end thereof disposed at the minimum fill level of the tank. A vapor vent fitting is also formed in the tank, to which any one of a plurality of different-length vent pipes can selectively removably be mounted with the inner ends thereof disposed at different levels between the maximum and minimum fill levels of the tank. The vent pipe communicates with the one lading conduit above the maximum fill level of the tank. An access opening is provided so that the vent pipe can be reached and changed from outside the tank.
In one embodiment the vent pipe communicates with the one lading conduit inside the tank and access thereto is had through the one lading conduit. In another embodiment the vent pipe communicates with the one lading conduit inside the tank, but access thereto is had through a separate access opening in the tank. In a third embodiment the vent pipe communicates with the one lading conduit outside the tank. A special tool is provided for facilitating mounting and demounting of the interchangeable vent pipes from outside the tank.
