Project Description

The California High-Speed Rail Authority (CHSRA), Caltrain, Santa Clara Valley Transportation Authority (VTA), and the City of San José (Partner Agencies) have been working together on a multi-phase plan to expand and redesign Diridon Station. The goal is to develop a world-class center of transit and public life that provides smooth connections between modes and integrate with the surrounding neighborhoods.

Electrified Caltrain, BART, and High-Speed Rail service will add to the trains, buses, and light rail that currently serve San José Diridon Station. The City of San José is adopting plans for substantial transit-oriented development near the station, which will bring thousands of new jobs and residents to the area. With these changes, Diridon Station is poised to become one of the busiest intermodal stations on the West Coast.

Scope of Services

Under this long-term project, RSE has managed all aspects of the program, including the Project Study Report, that required the following:

  • Identification and development of program alternatives

  • Conceptual engineering

  • Preliminary and final design services

  • Construction cost estimating

  • Funding source identification

  • Construction support. 


The project implementation cost was approximately $200 million. A key component of this high-profile, long term, multi-phase program was the successful coordination of multiple parties and stakeholders. For example, the program included coordination and negotiations with UPRR, Caltrans, CCJPA, VTA, ACE, local city agencies, and various public utilities. Coordination was also required with FTA, SHPO, Regional Water Board, and other regulatory agencies. Additionally, coordination was required with California High Speed Rail (CAHSR) and Positive Train Control (PTC).
