About Us

The San Joaquin Regional Rail Commission (SJRRC) is the owner and operator of the Altamont Corridor Express (ACE®) train service. In 1998 ACE began operations to meet the needs of commuters from the San Joaquin Valley, Tri-Valley, and Silicon Valley regions. Today, ACE operates four daily round-trips starting at the Cabral Station in Downtown Stockton, through the Tri-Valley, and into Downtown San Jose. ACE currently carries over 1.3 million riders a year and ridership has doubled since 2011. In 2015, SJRRC became the managing agency of the San Joaquin Joint Powers Authority (SJJPA), which is the manger and administer of Amtrak San Joaquins. Amtrak San Joaquins operates 7 daily round-trips from Bakersfield to Sacramento/Oakland and an extensive Thruway Bus service that reaches over 135 destinations in California and Nevada.

SJRRC is strategically aligned with ACE and the San Joaquins to bring transformational improvements to commuter and intercity passenger rail service in the San Joaquin Valley and the Northern California Megaregion. Its Valley Rail Program is a nearly $1B expansion that will connect new communities and increase existing service to increase its role in offering alternative transportation options to its service areas.
