This is the commonly referred to method of transferring fuel from a railcar to a truck without having it sent to storage first. There can be two types of transloading – fixed or mobile. A “fixed” transloader unit is usually a permanently mounted pump and metering skid that is positioned adjacent to a rail spur equipped with a railcar suction header. The railcars are spotted along the suction header for coupling to the railcar drain valve. The “mobile” transloader unit has wheels to accomplish the task and can be moved from railcar to railcar to empty them one-at-a-time.
