Do You Need a Real ID for Train Travel
For domestic train travel in the United States, a real ID-compliant driver license or state ID is required at TSA checkpoints for Amtrak routes that include airport-style security screening, effective May 7, 2025, according to the Transportation Security Administration TSA Real ID. A standard driver license without a star or a non-compliant ID will not pass security for these trips. For international train travel, a valid passport or, where applicable, an enhanced driver license or trusted traveler card is typically required by border authorities and rail operators such as Amtrak, SNCF, Eurostar, and Deutsche Bahn Amtrak.
Not all train journeys require ID checks. Many regional and commuter rail services within the United States, Europe, and Asia do not enforce real ID rules because they lack TSA-style screening or international border crossings. However, if your trip connects to an airport, crosses a national border, or involves a high-speed or long-distance service with security protocols, you must present an acceptable ID. Always check the specific train operator’s latest policy before booking, as rules can change based on security alerts or new regulations.
Accepted IDs for Train Travel
For U.S. domestic train travel with security screening, the TSA accepts real ID-compliant driver licenses or state IDs with a star, U.S. passports, passport cards, DHS trusted traveler cards such as Global Entry and SENTRI, and U.S. military IDs TSA Real ID. For international train travel, a valid passport is the most universally accepted document, while enhanced driver licenses and NEXUS cards are accepted at land and rail crossings between the U.S., Canada, and Mexico. Children under a certain age, often 18 for domestic travel and 16 for international travel, may travel without an ID if they are accompanied by an adult, but policies vary by operator.
Digital IDs and mobile driver licenses are not yet widely accepted for train travel security checks as of the latest public guidance from the TSA and major rail operators. Some states and countries are piloting digital identity systems, but physical documents remain the standard for boarding and screening. If you do not have a real ID-compliant document, you can use a U.S. passport or apply for a state-issued real ID at your local Department of Motor Vehicles or equivalent agency, which typically requires proof of identity, residency, and Social Security number.
How Real ID Rules Affect Train Bookings
Amtrak requires passengers to present a valid, real ID-compliant document or passport at check-in and boarding for routes that include TSA security screening, such as trips to and from certain airports Amtrak. Booking platforms and station agents may ask for ID details during purchase, and mismatched or expired documents can result in denied boarding. For international train services like Eurostar, Thalys, TGV, and Amtrak Cascades, operators align with national border control rules and require passports or other travel documents that meet the destination country’s entry requirements Eurostar.
Fines and penalties for traveling without a required ID vary by jurisdiction and operator. In the U.S., passengers without a real ID or alternative TSA-accepted document will not pass security and may miss their train or be rebooked at their own expense. In Europe, rail authorities and border agencies enforce passport and ID checks on international routes, and non-compliance can lead to denial of boarding or fines. To avoid disruption, travelers should verify ID requirements with the train operator and relevant government agencies before departure, keep documents accessible during the journey, and renew expiring IDs well in advance of travel dates
