With an aggressive air response, firefighters were able to fully contain a blaze in Acton on Tuesday that consumed 125 acres, including several structures and cars.
The northern Los Angeles County wildfire started burning around 4 p.m., said Supervising county fire dispatcher Robert Diaz. Low humidity and gusty winds in the region contributed to the quick speed of the fire's spread.
As of 6:30 p.m., firefighters believed they had "stopped the fire in its tracks" for now, according to L.A. County Fire Captain Mark Savage. Metrolink re-opened tracks north of Via Princess "at restricted speeds" and was making stops to Lancaster, according to its Twitter feed.
Contained by nightfall, fire officials allowed residents who were evacuated earlier in the day to return home that evening. Diaz said firefighters remained on the scene near West Crown Valley Road to monitor hot spots overnight.
No injuries were reported. The cause of the fire is being investigated.
