The San Joaquin Regional Rail Commission (SJRRC) is launching an effort to improve and expand the existing Altamont Corridor Express (ACE) rail service between Stockton and San Jose, California, as well as extension of the rail service to Modesto and Merced, California. The ACEforward program will strive to reduce travel time by at least 10 percent, and increase reliability of the existing ACE rail service. In the near term, ACEforward aims to increase existing service from 4 daily round trips to a proposed 6 daily round trips, extend to Modesto in Stanislaus County, implement safety and grade crossings improvements, and add track in key locations. ACEforward is also planning longer-term improvements to increase service to at least 10 daily round trips, provide weekend service, and extend to Merced. As of June 6, 2013, project leadership and funding for the Altamont Corridor has been transferred from the California High-Speed Rail Authority to the San Joaquin Regional Rail Commission.
