This bill addresses the effective date for specific adjustments to the rail passenger liability cap. It focuses on modifications to the liability cap as outlined in section 28103(a)(2) of title 49, United States Code, which are typically based on the Consumer Price Index. For any such liability cap adjustment that is scheduled to occur during calendar year 2026 , the bill mandates a change to its implementation timeline. Instead of its original effective date, the adjustment will now take effect 90 days after the notice required under section 11415(b) of the FAST Act is issued. This provision specifically targets and delays the effective date for these particular rail passenger liability cap changes.
