A rail port insert is provided. The insert comprises an outer casing comprising a tubular sidewall and a base, the sidewall and base defining a spatial volume therein, the base defining an inlet passage that extends through the base and that is fluid communication with the spatial volume, and an elastomeric body having a first end and a second end, the elastomeric body disposed within the spatial volume and affixed to an inner surface of the tubular sidewall, the base, or both an inner surface of the tubular sidewall and the base. The elastomeric body comprising a flow passageway having a length extending from the first end to the second end, the first end in fluid communication with the inlet passage of the base, the second end further comprising a depth-length and defining an orifice along the depth-length, the orifice moving from a closed position in the absence of any applied pressure within the flow passageway, to an open position when pressure is applied within the flow passageway. When the rail port insert is installed in a railhead port, the inlet of the outer casing is in fluid communication with a railhead conduit.
