The "Baby Changing on Board Act" aims to enhance family-friendly amenities on Amtrak trains by requiring the installation of baby changing tables. This legislation amends title 49 of the U.S. Code to mandate these facilities on specific passenger rail cars. Under the bill, all covered passenger rail trains —defined as those owned and operated by Amtrak and solicited for purchase after the Act's enactment—must include a baby changing table in at least one restroom per rail car. This requirement extends to ADA-compliant restrooms to ensure accessibility for all passengers. Furthermore, the bill stipulates that clear signage must be present to indicate the location of these baby changing tables within the restrooms, making them easily identifiable for travelers with infants.
