To establish limitations on advanced payments for bus rolling stock, and for other purposes.

This bill (HR 3586) modifies federal transit funding rules to allow transit agencies to make advance payments for new buses without requiring manufacturers to provide a performance bond. It sets strict limits: agencies may pay no more than 20% of the total bus purchase price upfront, and must have a signed contract with the manufacturer, preaward approval, and meet other existing requirements. The bill directly affects transit agencies receiving federal funds under Title 49 for bus purchases. It changes how agencies can structure payments but does not alter funding amounts or create new financial obligations. The key change is removing the performance bond requirement while imposing a 20% cap on advance payments.
