The FRA published in the Federal Register (83 FR 61709-10) on November 30, 2018, a notice to advise the public that FRA is rescinding the Notice of Intent (NOI) for the ACEforward Program.  The project sponsor has determined that the original scope for the ACEforward Environmental Impact Statement (EIS) is no longer consistent with regional planning efforts for improved rail service throughout the corridor.

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.

In addition, pertinent information about the project can be found at the project's FRA webpage:
