Hello,
Planning a possible visit to Harry Potter studios. Looks like the easiest oublic transit is from Euston Station to Watford Junction and then the shuttle bus to the studios.
It looks like I could use an Oyster card for the trip. However, from what I can tell there are direct trains and ones that are part of the London tube/overground system.
Would an Oyster Card work for both or only the tube system trains or could I hop on any train going from Euston station to Watford Junction?
Thank you!!!
