STOCKTON, Calif. — The Altamont Corridor Express locomotive fleet is now running solely on renewable diesel fuel, the commuter service’s parent agency, the San Joaquin Regional Rail Commission, has announced. The agency says the switch will reduce greenhouse gas emissions by 99% and is a key step toward its goal of net-zero-emission operations.

“Our commitment to reducing greenhouse gas emissions has taken a large step forward,” Brian Schmidt, the commission’s director of equipment services, said in a press release. “Our fuel partner, Valley Pacific, has been a key partner in this transition.”

Valley Pacific Petroleum Services supplies fuel for the ACE fleet of Siemens Charger and MPI F40PH-3C locomotives. The renewable diesel fuel is made from materials such as used cooking oil or inedible corn oil.

“Our customers have found that, compared to petroleum-based diesel, renewable diesel works better in their engines, produces less ash, and they’re happy it improves air quality and lowers their carbon footprint,” said Valley Pacific CEO Nathan Crum.
