The Sacramento Extension will use the Sacramento Subdivision between Stockton and Sacramento.{{cite report |url=https://cdn.acerail.com/wp-content/uploads/Valley-Rail-Sac-Ext-FEIR-Vol-I-Sept-2020.pdf |title=Final Environmental Impact Report: Valley Rail Sacramento Extension Project, SCH #2019090306 |volume=1 |author=AECOM |date=September 2020 |publisher=San Joaquin Regional Rail Commission |access-date=30 October 2024}}{{rp|ES-1;ES-8}} In the first phase of the Sacramento Extension, six new stations would be constructed along the line between Natomas and the current eastern ACE terminus in Stockton Downtown (Cabral) station;{{rp|ES-1;ES-6}} a layover facility would be built near the new Natomas station in that north Sacramento neighborhood for the second phase.{{rp|ES-8}} After the first phase, one ACE train would start from Natomas in the morning and continue to San Jose via Stockton, with a corresponding return trip in the afternoon;{{rp|ES-10}} two round-trip San Joaquins trains would be added, both with Natomas as the northern terminus, operating to either Fresno or Bakersfield.{{rp|ES-9}} The San Joaquins stop in Stockton would move from San Joaquin Street station to Downtown/Cabral.{{rp|ES-9}} South of Stockton Downtown/Cabral, San Joaquins would continue to operate on the Stockton Subdivision.{{rp|ES-9}}

In addition, the related North Valley Rail project proposes to extend service north from Natomas to Chico. Under the initial operating plan, two daily trains would depart Chico in the mornings, traveling south via Natomas and Stockton Downtown/Cabral; one would continue through and terminate at Union City, while the other would stay in Stockton for a timed transfer to San Joaquins trains. Two afternoon northbound trains would be provided for passengers returning to Chico.{{cite web |url=https://northvalleyrail.org/wp-content/uploads/2023/10/north-valley-rail-booklet-20230921.pdf |title=North Valley Rail (booklet) |date=September 2023 |publisher=Butte County Association of Governments |access-date=30 October 2024}}

The Merced Extension is divided into two phases, covering Lathrop to Ceres and Ceres to Merced, which will extend service to Ceres and Merced via Lathrop and Modesto. This extension will use the Fresno Subdivision, joining the existing ACE route at a new North Lathrop station, just north of Lathrop/Manteca station. The existing route uses the Oakland Subdivision from Niles to Lathrop and the rail junction between the Fresno and Oakland subdivisions will be rebuilt.{{rp|2-2;2-7;2-9}} Several new stations will be constructed and the line will be double-tracked, extending the eastern ACE terminus to Merced, where a new layover facility would be added.{{rp|2-10}}{{cite report |url=https://www.sjrrc.com/lathrop-ceres-extension-eir/ |title=Draft Environmental Impact Report: ACE Extension Lathrop to Ceres/Merced, State Clearinghouse #2018012014 |chapter=3: Description of Phase II Improvements |chapter-url=https://d2j5fyfnufxt9o.cloudfront.net/wp-content/uploads/3_0_PII-Descript.pdf |date=April 2018 |publisher=San Joaquin Regional Rail Commission |access-date=28 October 2024}}{{rp|3-3}} Under the initial operating plans, four trains would start at Merced (Ceres after the first phase) in the mornings, traveling to North Lathrop, with a timed transfer stop for passengers continuing westbound to San Jose.{{rp|2-23}}{{rp|3-18;3-19}} Three trains would continue from North Lathrop to Natomas, where they would be stored for the day; one train would operate a mid-day roundtrip from Natomas to Stockton and back.{{rp|2-21;2-22}} One train would continue to San Jose.

ACEforward was a project initiated by ACE in 2013 to increase ridership, primarily by improving service frequency and reliability over the existing Stockton–San Jose route, including a proposed tunnel through Altamont Pass, but also by expanding service east from Stockton further into the Central Valley. Full implementation of ACEforward was estimated at US$9.7 billion,{{cite news |last1=Holland |first1=John |title=Forty trains a day through Altamont at up to 125 mph?

ACE discontinued ACEforward in favor of a new Valley Rail project, which scaled back the older project's scope by focusing initially on the eastern expansion to Merced.{{cite report |url=https://www.sjrrc.com/lathrop-ceres-extension-eir/ |title=Draft Environmental Impact Report: ACE Extension Lathrop to Ceres/Merced, State Clearinghouse #2018012014 |author=ICF |date=April 2018 |publisher=San Joaquin Regional Rail Commission |chapter=1: Introduction |chapter-url=https://d2j5fyfnufxt9o.cloudfront.net/wp-content/uploads/1_0_Intro.pdf |access-date=30 October 2024}}{{rp|1-1}}

Amtrak California San Joaquins service connects Bakersfield with Stockton via the former AT&SF route through the California Central Valley; from the Stockton Diamond, most trains turn west to Stockton (San Joaquin Street) station enroute to Oakland–Jack London Square station, while the others continue north to Sacramento station via Stockton Downtown/Cabral and Lodi Transit Station.{{cite web |url=https://amtraksanjoaquins.com/train-service/ |title=The Train Service |publisher=Amtrak San Joaquins |access-date=28 October 2024}}

ACE service connects Stockton Downtown/Cabral with San Jose Diridon station via the Fresno, Oakland, Niles, and Coast subdivisions, incorporating the former Feather River Route through Altamont Pass. The ACE terminus in Stockton is approximately {{cvt|1.5|km}} from the Amtrak San Joaquins station on San Joaquin Street for Oakland-bound trains.

From east to west, the stations on the Merced Extension are:

The Lathrop Wye connection between the Fresno, Tracy, and Oakland subdivisions will be rebuilt as part of the first phase of the Merced Extension. Part of the reconstruction will include new at-grade crossings of the Fresno Subdivision at McKinley Avenue and S Airport Way.{{rp|5-1}} In addition, approximately {{cvt|51|mi}} of the Fresno Subdivision from Manteca to Merced would be double-tracked, in some cases upgrading existing siding tracks to mainline service.{{rp|2-13}}{{rp|2-10}}

When the first segment of the Merced Extension is complete, the initial plans are to operate four daily roundtrip trains between Ceres and North Lathrop, starting from Ceres in the mornings, with most continuing westbound passengers transferring to San Jose-bound trains (originating from Stockton) at North Lathrop. A temporary bus bridge would be provided between Ceres and Merced.{{rp|2-20;2-23;2-25}} Once the second segment is complete, the bus bridge between Ceres and Merced will be replaced by rail service. Four trains will originate from Merced instead of Ceres, of which three will run north to Natomas via North Lathrop station, where westbound passengers to San Jose would transfer. One train would run directly from Merced to San Jose. In the afternoons, three return trains would run from Natomas to Merced and one return train would run from San Jose to Merced.{{rp|2-28}}

The Valley Link project will extend rail service east from Dublin/Pleasanton station, the terminus of the Bay Area Rapid Transit Blue Line; Valley Link will eventually terminate at the North Lathrop station, serving as a transfer point between Valley Link and ACE.{{cite report |url=https://www.valleylinkrail.com/deir |title=Draft Environmental Impact Report: Valley Link, State Clearinghouse #2018092027 |date=December 2020 |author1=ICF |author2=AECOM |publisher=Tri-Valley—San Joaquin Valley Regional Rail Authority |access-date=31 October 2024 |chapter=2: Project Description |chapter-url=https://www.valleylinkrail.com/_files/ugd/95df9a_a39ee7f7463f4fd39536b82c661f0589.pdf}}{{rp|2-10}} Dublin/Pleasanton is approximately {{cvt|5|km}} north-northwest of the Pleasanton station currently served by ACE, and the Valley Link route generally would run parallel to and north of ACE between Pleasanton and Lathrop, using the median of I-580 west of Altamont Pass, the same Alameda County Transportation Corridor through the pass, and the Tracy Subdivision east of the pass.{{rp|2-12;2-13;2-15}}

From north to south, the stations on the Sacramento Extension are:

The (north-south) Sacramento Subdivision crosses the (east-west) Martinez Subdivision at the Haggin Wye,{{cite magazine |url=https://railfan.com/railfan-guide-to-sacramento/ |title=Railfan Guide to Sacramento |first=Adam |last=Pizante |magazine=Railfan & Railroad |date=August 2023 |access-date=4 November 2024}} east of the existing Sacramento Valley Station (served by Capitol Corridor and some San Joaquins trains) and bracketed by the planned Old North Sacramento and Midtown Sacramento stations (which will be served by ACE and San Joaquins) to the north and south, respectively. The tracks would be realigned just south of the wye.{{rp|Fig.2-8}}

When the Sacramento Extension is complete, San Joaquins and ACE both would add new trains. San Joaquins would add one roundtrip between Natomas and Fresno and another roundtrip between Natomas and Bakersfield.{{rp|2-21}} ACE would add one train originating from Natomas in the mornings, traveling south and west to San Jose via Stockton, with a corresponding return trip from San Jose to Natomas via Stockton in the evenings.{{rp|2-21}} In addition, with the completion of the first phase of the Merced Extension, trains originating from Ceres would travel north to Natomas via North Lathrop, returning in the evenings after storage and maintenance at Natomas. ACE also would operate one mid-day roundtrip from Natomas to Stockton and back.{{rp|2-21 to 2-22}}
