Yes, you absolutely need digital or physical photographs for both individuals named on a "Two Together" Railcard. This specific railcard is designed to provide a 1/3 discount on rail fares in the UK, but it is only valid when the two people named on the card are traveling together. Because the card is non-transferable and tied specifically to two unique identities, the rail authorities require a clear, passport-style photo of each person to be printed on the card (if physical) or displayed in the app (if digital). When applying online, you must upload two separate high-quality digital photos that clearly show the faces of both applicants without hats or sunglasses. If you are applying at a staffed station ticket office, you must bring two physical passport-sized photos with you. Conductors and ticket inspectors will check these photos against your physical appearance during ticket checks to prevent fraud. If you are found traveling with a discounted ticket but cannot produce a railcard that clearly identifies you via these photos, your ticket will be considered invalid, and you will likely be required to pay the full "Anytime" fare plus a potential penalty fare.
