The Altamont Corridor Express (reporting mark ACEX; formerly the Altamont Commuter Express) also known as ACE, pronounced "ace") is a commuter rail service in California connecting Stockton and San Jose.
It is named for the Altamont Pass, through which it runs. The service began October 19, 1998, with two trains each way, weekdays only. In November 2009 three trains a day each way began, and four trains a day in September 2012. There are ten stops along the 86 miles (138 km) route; travel time is about 2 hours and 10 minutes end-to-end. The tracks are owned by Union Pacific. ACE uses Bombardier BiLevel Coaches and MPI F40PH-3C locomotives. It is managed by the San Joaquin Regional Rail Commission and operations are contracted to Herzog Transit Services.

History and funding
The Altamont Commuter Express (the originally name) was established for San Joaquin County residents traveling to work in Santa Clara County. ACE trains are presently limited to morning departures from Stockton and return departures from San Jose in the afternoon. The trains was popular at first and survived a severe drop in ridership due to the dot-com recession of 2002. Struggles with freight traffic interference and track reconstruction prevented the addition of a fourth train until September 2012. The operation is funded by local sales taxes, with support from state and federal sources.
Service began under the governance of the San Joaquin Regional Rail Commission Joint Powers Authority formed in 1997 by Alameda, San Joaquin, and Santa Clara counties. The present Rail Commission has of one member each from the San Joaquin and Alameda county boards of supervisors, one BART representative, and representatives of five cities. Cost sharing for capital projects, excluding stations, during the initial 36 months of service was determined by the ACE Authority on a case by case basis and approved by each of the member agencies. The initial purchase of rolling stock, construction of stations, and other start-up costs, amounting to some $48 million, were covered primarily by a San Joaquin County transportation sales tax approved several years earlier, along with state and federal funding. Cooperative services agreements with the Alameda County Congestion Agency and the Santa Clara Valley Transportation Authority spell out funding of operations, maintenance and capital improvements. Currently, station improvements are the responsibility of the county in which the station is located. ACE pays the owner of the right of way, Union Pacific Railroad, about $1.5 million per year; it also uses about four miles (6 km) of Caltrain track in San Jose.
In Fiscal Year 2006-7 the 675 thousand ACE trips generated fare-box revenues of some $4 million, about 30% of the $13.3 million operating and administrative cost. Most of the annual operating costs are underwritten by San Joaquin, Alameda, and Santa Clara counties in proportion to the boardings and alightings in each county. San Joaquin County funds its $2.32 million contribution from a half-cent transportation sales tax (30% of the tax adopted in 1990 and renewed in 2006 is allocated to bus, bicycle, rail, and pedestrian programs. The Alameda County Congestion Management Authority pays its $1.8 million share from its half-cent transportation sales tax (1.2% of its Measure B budget). Santa Clara County’s $2.6 million share is paid by the Valley Transportation Authority, operator of the county’s light rail and bus system, which also contributes about $1.5 million for shuttle services that take ACE commuters from train stops to job sites. Miscellaneous revenues, of some $2.5 million are supplied from federal and state grants, including Congestion Mitigation and Air Quality funds. Each county absorbs its own administrative costs, estimated at $2.4 million annually.

San Jose to Great America
The northbound leaves San Jose's Diridon station and heads north on the main peninsula Caltrain tracks through the rail yards in Santa Clara, California. As the train passes under De La Cruz Avenue it leaves the Peninsula tracks and heads north. The train passes over Central Expressway just west of De La Cruz near the end of the runway of San Jose International Airport. The train then passes over U.S. Route 101 and proceeds along Lafayette Street. It passes to the east of California's Great America, a large substation, and the San Francisco 49ers training facility and 49ers future home Levi's Stadium before stopping at the Great America station under the Tasman Drive overpass.
Great America to Fremont
The train proceeds north along Lafayette Drive passing through a golf course and under Highway 237. It then turns north through the Alviso district of San Jose, passing just east of its abandoned marina. The train then heads out into the mudflats and sloughs of the bay. In the middle of the flats, the train passes through the sunken ghost town of Drawbridge. Next along the route are Cargill's (formerly Leslie's) salt evaporation ponds on both sides of the track where the train turns to the northwest. The train then passes a landfill before entering Newark, California. At Baine Avenue, the train makes a 90o right turn a few hundred yards from the point where the track from the historic Dumbarton rail bridge connects in. The journey continues northeast along Baine Avenue and crosses I-880. Just after crossing Fremont Boulevard, it arrives at the Fremont Amtrak station. A historic sign remains on the portion of the station to the south of the tracks. It refers to the city of Centerville, predating the city of Fremont, and includes the distance to both Ogden, Utah and San Francisco, with the distance to San Francisco calculated via the historic bridge.
Fremont to Pleasanton
The train leaves the Fremont station and turns east-northeast to head towards Niles Canyon. It crosses under the BART tracks and heads along Alameda Creek, but it does not interconnect with BART. It then turns north to enter Niles Canyon. The narrow canyon contains two rail lines (one is now partially abandoned), Highway 84, Alameda Creek, and the Hetch Hetchy Aqueduct. The other rail line in the canyon was the route of the 1869 Sacramento-to-San Francisco Bay extension of the historic First Transcontinental Railroad and is now used by the Niles Canyon Railway. The train passes through a 0.75-mile (1.21 km) long tunnel which cuts off one of the canyon's horseshoes. This tunnel was modified from its original configuration to accommodate intermodal double-stack freight trains. However, this left the track in poor condition, causing the train to reduce speeds from 45 mph (72 km/h) to 25 mph (40 km/h) in the summer, and down to 10 mph (16 km/h) during the rainy season. The San Joaquin Regional Rail Commission plans to rehabilitate the tunnel as part of their 10-year service improvement plan. Eventually the train emerges into Sunol and heads north alongside I-680. It then passes through the center of Castlewood Country Club before pulling into the station in Pleasanton.
Pleasanton to Livermore
The train leaves the Pleasanton station and turns east-northeast, paralleling Stanley Boulevard. It travels along Stanley Boulevard between Heron Pond and the old quarries. It enters Livermore as it crosses Isabel Avenue, and turns more northwest as it crosses Murrietta Boulevard. It then stops in downtown Livermore. It then passes under First Street (formerly highway 84) and stops under Vasco Road near the northwest corner of Lawrence Livermore National Laboratory.
Livermore to Tracy
The train then turns north at the edge of the hills and passes I-580. It then parallels Altamont Pass Road. The path of the original 1869 Sacramento-to-San Francisco Bay extension of the First Transcontinental Railroad can be seen on the right, and then on the left for several miles. The track is not there, but the bed and some markers remain. The train, now following tracks built for the Feather River Route, makes numerous turns as it ascends the Altamont Pass. A large quarry and several wind farms are visible. The route eventually turns south and then passes under westbound 580 and over eastbound 580. The entrances for a pair of short tunnels on the older route under the summit remain just east of the path. The train then descends from the pass in a southeasterly route before crossing under 580 a third time and over the California Aqueduct and the Delta-Mendota Canal before reaching the valley floor. The train then brushes Tracy, following Linne Road at the very southern edge of the city.
Tracy to Lathrop/Manteca
Lathrop/Manteca to Stockton
It then proceeds north past Sharpe Army Depot and into the final station in the southeast portion of downtown Stockton. The train frequently reaches top speeds just over 80 mph (129 km/h) on these relatively straight, flat routes.
Tickets and fares
ACE tickets are available at select stations and on ACE's website. They are available in one way, round trip, 20 trip, weekly, and monthly passes. Fares are distance-based, ranging up to $11.75 for a one-way adult ticket (as of November 2011).
In association with the California High Speed Rail Authority, plans are being generated to upgrade the current system to provide faster, more regular service. This will be done gradually, starting with the ACEforward program that will include new track, stations, and possibly an extension to Modesto and Merced.
