Board Approves Staff Recommendation for Eldorado
To Supply Up to 600 Forty-Footers with L9N Engines

The board of the Los Angeles County Metropolitan Transportation Authority has approved a staff recommendation to purchase 295 forty-foot compressed natural gas-fueled transit buses from ElDorado National – California. If contracted, ENC will be a new supplier to the agency.

LA Metro’s Strategic Planning for Metro’s Transition to Zero Emission Buses report was released earlier this month. The Cummins Westport low-NOx engines powered by RNG/renewable natural gas are, arguably, the closest thing to near-zero that’s economically feasible today.

The buses will have super low-NOx 8.9-liter engines from Cummins Westport, to be designated L9N, replacing today’s ISL G Near Zero. The first of the production vehicles are expected to be delivered in spring 2018.

“This engine gives our customers the most affordable path to zero-equivalent emissions and the benefits of performance and reliability described by California’s South Coast Air Quality Management District as equivalent to an electric vehicle,” Cummins Westport president Rob Neitzke said in an NGVAmerica release.


The LA Metro board also approved an option for 305 additional 40-foot buses, making for a potential total of 600 for ENC.

“Transit agencies around the nation continue to realize the benefits of renewable natural gas,” NGVAmerica interim director Katheryn Clay said in the association announcement.

“Diesel emissions continue to plague our environment,” she said, “especially in cities like Los Angeles. But together, with the leadership from agencies like LA Metro, we can use natural gas powered vehicles to clean up the air and the environment in and around our communities today.”

‘Everything Going Forward Will Be Low-NOx’

Also according to NGVAmerica, LA Metro will also begin retrofitting its buses with the Cummins Westport low NOx CNG engines. The ISL G is certified to for emissions 90% lower than the U.S. EPA’s NOx limit.

“Everything we do going forward will be the low-NOx engine,” says LA Metro vehicle technology director John Drayton. He noted that the agency has been operating two New Flyer buses with the ISL G Near Zero engine, has logged nearly 100,000 miles, “and we haven’t had a hiccup.

“There has not been a mechanical issue with the engine at all,” he told F&F.

LA Metro is expected t make increased use of Redeem brand RNG/renewable natural gas from Clean Energy Fuels (F&F, May 29).

Cummins Westport has meanwhile launched a new Natural Gas Playbook website with information on its near-zero engines, a trio of which were launched at last month’s ACT Expo in Long Beach, Calif. (F&F, May 5).

CNG and ZEV Artics for LA Metro Too

The Playbook, the company says, “provides the opportunity to connect with Cummins and Cummins Westport experts to answer questions and support the successful adoption of natural gas into truck, refuse, school bus, and transit applications.”

Watch too for significant news on 60-foot CNG and battery electric buses for LA Metro in the coming weeks, as the agency this month released a Strategic Planning for Metro’s Transition to Zero Emission Buses report. The key goal? A 100% Zero Emission Bus Fleet by 2030. Stay Tuned!
