Yes, you can use the Trainline app without internet to access your tickets, provided you have downloaded them beforehand. In 2026, the app features a "Digital Ticket" system where tickets are stored locally on your device's "My Tickets" page. Once a ticket is downloaded and activated (which should be done while you still have a connection), the barcode remains visible and scannable by station gates and conductors even in "dead zones" or while in airplane mode. The app also stores essential journey details like departure times and platform numbers for offline viewing. However, you will still need an active internet connection to purchase new tickets, see "Live" train delays, or receive real-time platform changes. For 2026 travelers, it is a "pro-tip" to activate your ticket just before boarding to ensure it's ready for an offline scan during the journey.
