The San Joaquin Regional Rail Commission (SJRRC) is governed by a Board of Directors consisting of six full-voting members from San Joaquin County and two special-voting members from Alameda County. SJRRC owns, operates, and is the policy-making body for the Altamont Corridor Express (ACE) service, which has been transporting passengers between the Central Valley and Bay Area since 1998. In 2013, SJRRC became the managing agency of the San Joaquin Joint Powers Authority (SJJPA), which oversees the San Joaquins Intercity Passenger Rail Service.
