University students in London have several options for discounted public travel, primarily through the Student Oyster card and other schemes. The Student Oyster card is a photocard that offers eligible students a 30% discount on most Transport for London (TfL) services, including the Tube, buses, trams, DLR, London Overground, and some National Rail services within London. This discount applies to off-peak travel on the Tube, DLR, London Overground, and National Rail services, as well as all travel on buses and trams. However, the discount does not apply to peak travel on the Tube, DLR, London Overground, and some National Rail services.

To be eligible for the Student Oyster card, students must be enrolled in a full-time course at a recognized university or college in London, be aged 18 or over, and have a valid student email address. The application process is conducted online through the TfL website, where students need to provide proof of their student status and a digital photograph. There is a £10 refundable deposit required for the card, which is typically received within a few weeks.

In addition to the Student Oyster card, students can also benefit from the 16-25 Railcard, which offers a third off the price of most rail fares in the UK. This railcard is valid for one year or three years and can be purchased online or through the Railcard app. Some train operating companies (TOCs) may also offer their own student discounts, which can be checked on their respective websites.

For students who travel frequently, TfL operates a daily and weekly capping system, which means that once a certain amount is spent on travel within a day or a week, any further journeys are free. This system applies to both Student Oyster cards and contactless payments. Additionally, some universities in London may offer their own discounted travel schemes, which students should check with their university's student services department.

Overall, university students in London have several options for discounted public travel, including the Student Oyster card, the 16-25 Railcard, and potential discounts from train operating companies. By taking advantage of these discounts, students can significantly reduce their travel costs and make it easier to get around the city.
