State trains may run on ACE lines
Interconnect would put South County at high speed hub

California High-Speed Rail trains could one day run on Altamont Commuter Express tracks possibly allowing Manteca-Lathrop residents to board a train in their own backyard to reach Sacramento.

The ACE high speed rail system that will have its own distinctive green and gold electric trains for Northern San Joaquin Valley to Bay Area commuting is being designed to allow such a dual use.

It would mean high speed service could run on one track from San Jose to Los Angeles or San Jose to Sacramento. It opens the door to the possibility that the future ACE high speed trail station planned for Tracy could serve as a third access point for San Joaquin County residents to board Los Angeles bound high speed trains in addition to Stockton and Modesto. If California high speed trains run from Sacramento to San Jose partially on the ACE lines it could also mean the future ACE high speed station likely to go on Louise Avenue could be used to board state high speed rail trains going north.

Whether that happens when the dual system is in place depends on commuter objectives and travel times.

The ACE system would link with the California system in Modesto, Stockton, and San Jose. Both ACE and California High-Speed Rail trains would run at reduced speeds through the ACE system except crossing the Altamont Pass where speeds could approach 200 mph.

The Altamont Commuter Express High-Speed Rail Project is conducting three meetings on proposed routes and future stations on Thursday, Feb. 24, from 6:30 to 8:30 p.m. at the Tracy Transit Station, 50 E. Sixth St. A second meeting is planned for Livermore on March 23 and a third meeting in Santa Clara on March 7. For those who can’t attend a meeting, you can participate in the online Webinar on Thursday, March 10, from 11 a.m. to noon. Attendees can join five minutes prior to the event by going to The event number is 593 883 927. The event password is AltamonT1.

The ACE high speed route to Modesto will go down the Highway 120 Bypass median and then either curve southward after crossing Highway 99 and rejoins the Union Pacific corridor in the vicinity of the proposed McKinley Avenue interchange about a mile south of Austin Road to continue south, or go east to Escalon and then follow the Santa Fe Railroad corridor into Modesto.

A station is likely to be built adjacent to the Main Street overpass in Manteca.

There are two routes being considered through Lathrop for the San Jose to Stockton and ultimately Sacramento service.

•One would skirt River Islands at Lathrop and travel along the Interstate 5 corridor with a station at Louise Avenue.

•The other would follow the existing ACE alignment into Stockton via the Lathrop/Manteca rail station at West Yosemite Avenue.
