Altamont Commuter Express Service

In May 1997, the Alameda County Congestion Management Agency (ACCMA), the San Joaquin Regional Rail Commission, and the Santa Clara Valley Transportation Authority entered into an agreement to create the Altamont Commuter Express (ACE) Joint Powers Authority which operates the ACE Service. The ACE service operates Monday through Friday two roundtrip commuter trains between Stockton and San Jose and one additional roundtrip commuter train along the same route between Lathrop, in San Joaquin County and San Jose. The ACCMA funds the Alameda County share of the ACE service operations with Measure B funds. Measure B is a one-half cent sales tax approved by the voters of Alameda County in November, 2000. The use of the Measure B revenues is overseen by the Alameda County Transportation Improvement Authority. The ACE service will receive 2.12% of the net revenues of Measure B for ACE Service Operations.
