The main purpose of the Baby Changing on Board Act is to ensure that Amtrak trains are equipped with baby changing tables in their restrooms. This legislation aims to improve the convenience and comfort for families traveling with infants by providing a designated space for changing diapers. Key provisions of the Act require that all passenger rail cars operated by Amtrak must have at least one restroom equipped with a baby changing table. This includes restrooms that meet the standards of the Americans with Disabilities Act, ensuring accessibility for all passengers.
