San Joaquin Regional Rail Commission (SJRRC) is proposing to expand ACE passenger rail services in the San Joaquin Valley utilizing the Union Pacific Railroad (UPRR) rail network. JMA is currently designing the track and at-grade crossing improvements for the Elk Grove, Ceres and Ripon stations. This work includes over 15-miles of new track, including secondary mainline, 4 industry track improvements, a 3/4-mile track shift, 3 at-grade crossing improvements, the Ceres Layover Facility, and associated track grading and drainage. JMA coordinated extensively with UPRR and developed numerous alternatives for track configuration to support the station designs. This included alternatives for maintaining existing industry connections where applicable. UPRR has continuously updated its CAD and design standards and JMA has adapted quickly to these changes to ensure complete submittals in a timely manner. Additionally, JMA is leading the Ceres to Turlock Double Tracking segment as Prime. This Project includes construction of new track and track upgrades to provide a continuous second mainline track along the UPPR Fresno Subdivision stretching approximately 6 miles. The project also includes improvements to 11 at-grade crossings.
