During AGM weekend I went over to the factory and saw something sticking out of the side of the building that I hadnt notice before. Good sized pipes overhead as if it could be a fueling arm similar to something back in the day when locomotives would take on water. With 3 machines on site making fuel they are going to need tankers standing by.

Tank cars built after November 30, 1970, must not exceed 34,500 gallons capacity or 263,000 pounds gross weight on rail. They go as small as 4,000 gallons, but the ones you typically see (fuel and organics) are around 10,000 to 30,000 gallons.
