Interrail is only valid in trains (the train operating companies listed here). In London, this includes London Overground, Southeastern, Tfl Rail (Crossrail) and Thameslink. It does however not include the tube, tram or bus lines.

Alright thank you! I tried adding a trip with Thameslink but it didn't work. Will it be valid if I add it manually? 

What does "it didn't work” mean? Is the train not in the planner? If there's an error message, then please post a screenshot, or otherwise a screenshot of where you get stuck.

Adding a train manually is always OK.

Note that a very few stations are combined \TfL and Rails+there you MAY have quite some trouble with staff to enter, as they are mostly used to underground users.

The trips on bus or metro you can simply pay with your bankpass-there is a daily limit depending on on which zones you travel and if you use bus or more.

Hi

you mention its valid for the interrail. how about the eurail? Is the eurail pass valid on most underground and subways in london and amsterdam?

Interrail and Eurail have the same validity and function the same way, the only difference being European (Interrail) customers have restrictions on using it in their home country.

The advice above, as with all other on these boards applies equally to Eurail.

As a rule the passes are not valid on city metro/tram/bus networks. Please read the pages on the Eurail site and the Rail Network guides section on the app for more details about validity in each country.

Thank you for the swift reply. I assume metro/tram/bus networks is not the under and above ground in London. So therefore the eurail pass works?

Thank you

Hi

im a little concerned if I buy the eurail ticket and there is no availability on the train. The system only tells me the price of the seat reservation. Does that mean there are seats?

I looked from Brussels to London and it gave me a price for the seats on the 22nd. Does that mean there is availability?

please if you can clarify because I don’t want to buy it and there are no seats on the trains
