AB 599 California Assembly · 2025-2026 Regular Session

Short-Line Railroad Improvement Program.

Summary
Existing law requires the California Transportation Commission to establish a competitive funding program, commonly known as the Short-Line Railroad Improvement Program, to provide funds to the Department of Transportation or regional transportation planning agencies, or both, for short-line railroad projects such as railroad reconstruction, maintenance, upgrade, or replacement. Existing law appropriates up to $7,200,000 from the Trade Corridors Improvement Fund to the program and makes those moneys available for encumbrance or expenditure until June 30, 2028. This bill would extend the availability of those moneys for expenditure by one year. By extending the expenditure date of those moneys, the bill would make an appropriation. In order to receive funding from the Short-Line Railroad Improvement Program, existing law requires at least 30% of the total project cost to be provided from nongovernmental sources. This bill would authorize, for a project under the program for a publicly owned railroad, those funds to be provided from private funds, local funds, or state or federal funds not allocated by the commission on a project-specific basis.

What changed between versions

02/13/25 - Introduced 06/11/26 - Amended Senate · 5 edits · Jun 11, 2026
MODERATE
AB 599 was substantially expanded in the Senate to add an entirely new topic: amendments to the Short-Line Railroad Improvement Program under Government Code Section 8879.52. The original hazardous waste public notification provisions were retained but renumbered. The new railroad provisions extend fund availability by one year and relax matching requirements for publicly owned railroads, making this a bill that now addresses both environmental regulation and transportation funding.
SCOPE

The bill now includes amendments to Government Code Section 8879.52 relating to the Short-Line Railroad Improvement Program, a topic completely absent from the original introduced version.

FISCAL

The availability of funds appropriated for the Short-Line Railroad Improvement Program is extended by one year, from June 30, 2028 to June 30, 2029.

The appropriation designation changed from 'no' to 'yes' because extending the expenditure date of existing appropriated moneys constitutes a new appropriation under California law.

ELIGIBILITY

For publicly owned railroads seeking program funding, the 30 percent matching requirement is relaxed: funds may now come from private funds, local funds, or state or federal funds not allocated by the commission on a project-specific basis, rather than being limited to nongovernmental sources only.

TECHNICAL

The full text of Government Code Section 8879.52 is now included in the bill, covering TCIF corridor funding minimums, Colton Crossing project conditions, reporting requirements, and program guidelines for short-line railroad projects including performance metrics and a 15-year useful life requirement.
