Logistics company Twin Eagle has started receiving its first shipments of frac sand at its new rail yard just south of San Antonio.
The Houston-based company reported that a train with 130 railcars of frac sand arrived at the Mission Rail Park in Elmendorf on May 8 followed by a second train with the same number of railcars on May 15.
With each rail car capable of carrying 100 tons of frac sand, the two train shipments each carried an estimated 13,000 tons of frac sand.
Twin Eagle Senior vice president Jason Jennaro told the San Antonio Business Journal that the two shipments of frac sand are “historic,” noting that they are among the largest ever moved in the Eagle Ford and in the United States.
“The record that Union Pacific has is 135 cars,” Jennaro said.
A third train carrying another 130 railcars of frac sand is expected to arrive at the company’s rail yard next week.
Originally opened in March 2014, the Twin Eagle rail site added six silos on May 6. Together, the silos can store 300 railcars worth of frac sand while crews on a rail yard are able to load a truck headed to the oil field in less than two minutes.
Twin Eagle has another railsite in Laredo to service the southern end of the Eagle Ford and is building a similar site in Big Springs to service the Permian Basin.
