Los Angeles International Airport (LAX) has electrified the track at the Maintenance & Storage Facility for its automated people mover (APM) system.
This development will enable the first test runs of the new rail system later this year.
The APM is an electric train system that will operate on a 2.25-mile elevated guideway, serving six stations.
Once operational, the system will run 44 train cars, each of which will be able to carry 50 passengers and their luggage at a maximum speed of 47 miles per hour.
The trains will be available at each station every two minutes during peak hours.
This system aims to reduce traffic surrounding the airport and help cut carbon emissions.
Alongside being fully electric, the train cars will generate a portion of their own power through regenerative braking. In addition, the command centre and maintenance facility will generate nearly half of their power from solar energy.
