The invention relates to a transfer box sewage discharging mechanism for a train excrement collecting system and the train excrement collecting system. The transfer box sewage discharging mechanism comprises a transfer box, a plug valve and a driving mechanism, wherein the plug valve is installed on the transfer box, the plug valve is driven by the driving mechanism to vertically move so as to open or close a pollution discharge port in the bottom, and the side face of the transfer box is provided with a mounting bin concaved inwards towards the center; the plug valve is installed in the mounting bin in an embedded manner from the side face, the plug valve is composed of a valve body, a valve plug and a valve deck, the valve plug is installed in the valve body, the valve deck is fixed to the top of the valve body, the driving mechanism is fixed to the valve deck, an output rod of the driving mechanism is fixedly connected with the valve plug, and the valve body is an integrally-cast structural part; and the valve body is welded to a box body of the transfer box. The sewage discharging mechanism is simpler in structure; and the plug valve is integrally installed from the side face of the transfer box, so that not only is manufacturability is good, machining and manufacturing are easy, but also daily maintenance cost can be favorably reduced.
