Debit Cards: At staffed stations, debit cards must carry a credit-card network logo and are processed as credit transactions. PIN-only debit cards are not accepted for ticket purchases. Online Payments: Amtrak.com and the Amtrak app accept Apple Pay, Google Pay and PayPal, as well as eligible cards, gift cards, rewards points and eVouchers. Station Purchases: Cash is accepted at staffed stations; exact change is preferred. Onboard Purchases: Don't rely on buying your ticket aboard the train as a substitute for booking ahead. Ticketing rules and availability depend on the circumstances.
