The bill establishes a Washington State Amtrak Cascades Passenger Rail Advisory Committee, which will be convened by the department to provide information, advice, and recommendations on various issues affecting passenger rail service. The committee's focus will include performance improvements, station locations, on-time performance, multimodal connectivity, and policy initiatives that benefit the public and the environment. Additionally, the committee will explore grant opportunities to support passenger rail and report on progress towards goals set for Amtrak Cascades service.

The membership of the advisory committee will consist of representatives from various sectors, including state departments, advocacy groups, transit agencies, and Amtrak, among others. Members will serve three-year terms, with the committee required to meet quarterly and elect its officers annually. The committee will also provide an annual report starting December 1, 2027, detailing its activities and recommendations. Members will serve without compensation but can receive reimbursement for travel expenses.
