new extension to Modesto in addition to additional daily round trips. Long term goals included upgrades to the existing corridor to allow as many as 10 daily round trips, extension to Merced and electrification of the line from Stockton to San Jose. Also under studied were possible connections with BART at Union City or the Tri-Valley via traditional ACE rail, diesel multiple units, or bus bridges. This connection is planned to be facilitated by the Tri-Valley-San Joaquin Valley Regional Rail Authority. Altamont Corridor Vision The state senate allocated $400 million in revenue from a gas tax increase to ACEforward expansion. ACE was awarded $500.5 million in April 2018 for expanded service to Ceres and Sacramento to provide more rail service and connections within the Central Valley. Service is expected to begin from Ceres by 2023 with interim bus bridge service to Merced until that segment of Union Pacific right-of-way is upgraded. Four trains will depart Ceres in the mornings, and one train may make the complete run to San Jose with others transferring passengers at North Lathrop. By 2019, the plan had come to be called the Altamont Corridor Vision, with an expected price of $9.7 billion, allowing ACE to run up to six weekday round trips in 2023 with the goal of ten weekday round trips once additional track infrastructure is completed. ACE and the Tri-Valley-San Joaquin Valley Regional Rail Authority sought funding to construct a shared tunnel under Altamont pass in order to speed service and increase reliability. The Union Pacific right of way between Ceres and Lathrop will be double tracked to facilitate passenger service. platforms are being extended to accommodate longer trains. Valley Rail Valley Rail is the project to route ACE and Amtrak San Joaquins along the little-used Sacramento Subdivision between Stockton and Sacramento. Six new stations would be constructed along the line with a layover facility at Natomas. Trains would run the length of the line from Natomas to San Jose or Ceres with a midday short turn to Stockton. A Draft Environmental Impact Statement was released in 2020, with services expected to begin no later than 2023. The North Elk Grove station was eliminated from planning in September 2020. The project received funding via California's Transit and Intercity Rail Capital Program in 2023, by which time the project was expected to open in phases beginning in 2025.
