The purpose of this legislation, known as the Baby Changing on Board Act, is to ensure that Amtrak trains provide facilities for parents traveling with infants. Specifically, it mandates the installation of baby changing tables in the restrooms of passenger rail cars. This aims to improve the convenience and comfort of traveling families. Key provisions of the act include the requirement that all newly built passenger rail cars operated by Amtrak or other federally assisted intercity rail services must have at least one restroom equipped with a baby changing table.
