A siphon drainpipe system and method for use in a railway tank car includes a railway tank car having a tank at least partially defined by a generally elongate hollow cylinder having closed ends. The tank includes an upper surface and a lower surface, and forms a generally enclosed interior portion. A nozzle is coupled with the upper surface of the tank. A siphon pipe which extends from the nozzle toward the lower surface of the tank is coupled with the nozzle. The siphon pipe is at least partially disposed within the interior portion of the tank. In accordance with a particular embodiment of the present invention the siphon pipe includes a generally rigid, metallic portion disposed adjacent the upper surface of the tank, and a generally flexible portion disposed adjacent the lower surface of the tank.
