The Altamont Commuter Express, or ACE for short, is a commuter rail line that operates in Northern California. The service connects San Jose with Stockton along an 86 mile route. ACE has 10 stations stops with another 2 proposed stops. The ACE stops are: San Jose Diridon, Santa Clara (University/ Caltrain station), Santa Clara (Great America), Fremont, Pleasanton, Livermore, Vasco Road, Tracy, Lathrop/Manteca, and Stockton. The two proposed ACE stops are at Amtrak's Modesto and Merced stations. ACE trains share their route with Caltrain, Amtrak's Capitol Corridor, San Joaquin, and Union Pacific freight trains. ACE has 6 locomotives with 4 on order and 30 passengers cars (21 coaches and 9 cab-cars). ACE's locomotive fleet consist of 6 MPI F40PH-3Cs with 4 Siemens SC-44 Chargers to be delivered in late 2019. ACE's 30 passenger cars are Bombardier Series VI Bi-Level cars. ACE trainsets are typically between five to seven cars in length with the F40s leading trains into San Jose and the cab-cars leading trains to Stockton. ACE operates 4 round trips per weekday, but doesn't provide service on weekend or holidays. ACE equipment is kept and maintained at their facility just south of Stockton with trains also being stored in a storage yard just south of Caltrain's Tamien station.
