ABSTRACT OF THE DISCLOSURE A valve attachment flange comprising the lading outlet for a railway tank car is placed in an insulative space between a heat element heated fluid medium carrying heat ducts and the bottom of the car. The outlet is surrounded by a heat chamber in fluid flow communication with the heat ducts of the heat elements whereby the heat chamber surrounding the outlet is efficiently heated simultaneous with the heating of the lading by the heat element to promote flow of lading from the tank. This arrangement promotes fast efficient heating of the lading on top of and adjacent the valve and enables a valve attached to the recessed attachment flange to extend downwardly from the bottom of the car a lesser amount than conventionally mounted valves.
