Rail Transit

Altamont Corridor Express (ACE)

The San Joaquin Regional Rail Commission (SJRRC) owns and operates Altamont Corridor Express (ACE) rail, which serves commuters between the Northern San Joaquin Valley and the Bay Area.

Altamont Corridor Vision

The Altamont Corridor Vision is a long term plan to establish a universal rail corridor connecting the San Joaquin Valley and the Tri-Valley to San Jose, Oakland, San Francisco, and the Peninsula. This project will aid in reducing congestion, decreasing travel time, improving efficiency, and making overall improvements across the northern California area.
