Significant Historical Milestones
In 1998, the Altamont Corridor Express began operating 2 daily trains from the Central Valley to the Silicon Valley. Today ACE operates four weekday trains from the Central Valley to the Bay Area with stops in San Joaquin, Alameda, and Santa Clara counties and transports over 1 million passengers annually.
With special weekend trains taking passengers to Levi Stadium for the 49er football games and to anticipated special events such as the Great America Amusement Park and the San Jose Jazz Festival, ACE is helping community members enjoy their weekend as much as they're enjoying their stress-free ride to work through the week.
Stacey Mortensen is the Executive Director of the San Joaquin Regional Rail Commission and a visionary leader in the field of transportation. Stacey's ambitious goal is to modernize the existing ACE train and dramatically expand service to cities in the Central Valley and San Francisco Bay Area. Stacey is a true consensus-builder and works with community leaders and elected officials to create partnerships for success in transforming the Valley's commuter rail infrastructure.
