The largest frack sand unit train shipped to date in North America arrived at Rangeland Energy’s RIO Hub near Loving, N.M., the company said.

The RIO Hub is part of Rangeland’s RIO system serving oil and gas producers in the Delaware Basin. The 150-car unit train carried 16,500 tonnes (33 million pounds) of frack sand from Ottawa, Ill. Operator BNSF Railway Co. transferred the train’s service in Clovis, N.M., to Southwest Railroad Inc., its short-line railway partner.

The unit train arrived on Oct. 2 and the sand was stored at the hub, Rangeland said.

Rangeland Energy is based in Sugar Land, Texas.
