Transit and Intercity Rail Capital Program


The Transit and Intercity Rail Capital Program (TIRCP) was created by Senate Bill (SB) 862 (Chapter 36, Statutes of 2014) and modified by Senate Bill 9 (Chapter 710, Statutes of 2015), to provide grants from the Greenhouse Gas Reduction Fund (GGRF) to fund transformative capital improvements that will modernize California’s intercity, commuter, and urban rail systems, and bus and ferry transit systems, to significantly reduce emissions of greenhouse gases, vehicle miles traveled, and congestion. Through the six cycles of TIRCP funding, the California State Transportation Agency (CalSTA) has awarded $9.8 billion in funding to 125 projects throughout the state. The legislation of these bills is established in Sections 75220 through 75225 of the Public Resources Code (PRC). Assembly Bill 398 (Chapter 135) extended the Cap-and-Trade Program that supports the TIRCP from 2020 through 2030. SB 1 (Chapter 5) continues to provide a historic funding increase for transportation with funds directed to the TIRCP from the Public Transportation Account for new programming.

AB 180 amended the Budget Act of 2021 (Chapters 21, 69 and 240 of the Statutes of 2021) to appropriate $3.63 billion of General Fund to the Transit and Intercity Rail Capital Program and $350 million of General Fund for High Priority Grade Crossing Improvement and Separation projects. CalSTA awarded $2.54 billion of this funding to existing projects as the first grants of TIRCP Cycle 6 on January 31, 2023, and awarded $690 million to new projects on April 24, 2023.


The TIRCP was created to fund transformative capital improvements that modernize California’s intercity rail, bus (including feeder buses to intercity rail services, as well as vanpool services that are eligible to report as public transit to the Federal Transit Administration), ferry, and rail transit systems (collectively referred to as transit services or systems inclusive of all aforementioned modes unless otherwise specified) to achieve all of the following policy objectives, as established in Section 75220(a) of the PRC:

  1. Reduce emissions of greenhouse gases
  2. Expand and improve transit service to increase ridership
  3. Integrate the rail service of the state’s various rail operations, including integration with the high‐speed rail system
  4. Improve transit safety

Additionally, Section 75221(c) of the PRC establishes a programmatic goal to provide at least 25 percent of available funding to projects that provide a direct, meaningful, and assured benefit to disadvantaged communities.
