At Metrolink, we value our role in creating a more sustainable future for our riders and the communities we serve. 

Metrolink is committed to the goal of cleaner air in Southern California. We work with various transportation agencies throughout the region to offer our riders more sustainable and efficient ways to reach their Southern California destinations.

Taking the train is the smartest, cleanest and greenest way to travel.

Stats and Facts

Metrolink removes approximately 8,500,000 weekday automobile trips per year.

Weekday ridership is approximately 40,000 boardings.

22,000 bikes are carried on Metrolink trains each month.

Metrolink trains provide the same capacity as adding up to two new freeway lanes on adjacent freeways during peak commute times.

Tier 4 locomotives use up to 8 percent less fuel.

Metrolink’s Fuel Conservation Program has reduced fuel consumption by thirteen percent, or 853,000 gallons, per year.

Investing in a Cleaner Commute

Our commitment to environmental sustainability is reflected in the investments we make. Here are some of the many ways Metrolink has invested in a cleaner future for Southern California:


Smarter, Safer Train Operations
Programs and Technologies Reduce Emissions and Noise

Metrolink’s Fuel Conservation Program took effect in 2012 to reduce environmental impacts. By 2014, train idling was cut by 35% system-wide, and by 50% at the Central Maintenance Facility (CMF), where yard operations were modified to reduce service time and noise.

Metrolink boosted its Plug-In Program by 55%, adding more plug-in stations that supply electric ground power to rail cars during testing and inspection at CMF. This technology enables trains to run on electricity for a portion of their daily servicing and maintenance routine, rather than relying on locomotive power, and so reduces locomotive engine emissions.

Once a train has been serviced, tested and inspected, it is staged for departure. In 2014, Metrolink purchased an electric rail car mover to perform these operations, further reducing locomotive emissions and noise.

In 2015, electric forklifts replaced diesel forklifts, and Metrolink amended its policy on the activation of bells, reducing noise by 85%.

Less time idling means cleaner air. Auto-Engine Start/Stop (AESS) technology prevents excessive idling while reducing fuel use and emissions. Installation of AESS on Metrolink’s locomotives was funded in part by South Coast Air Quality Management District’s (AQMD) Carl Moyer Program, which focuses on cleaning the air by replacing older heavy-duty diesels with electric, alternative-fuel or cleaner diesel technologies.

Positive Train Control (PTC) is a life-saving technology which also conserves fuel by more gradual and controlled acceleration and deceleration, thereby conserving fuel. Learn more about PTC here.
