How to get to Warner Bros. Studio Tour London - by train 2024

Central London – Watford Junction

Watford Junction Railway Station is the closest that public transport from Central London will get you to the Warner Bros. Studio Tour London. You will find it marked on the London Underground map in the top left.

There are various permutations you can get to Watford Junction from the London area but from Central London the fastest and simplest option are trains running from Euston Railway Station.

How long will I need to allow for travel from Euston to Watford?

There are two types of train that travel between Euston and Watford Junction. The trains that are part of the London Overground whose trains stop at every station that take around 50 minutes and the trains that belong to the national railways (Midland Railways) where Watford Junction is often the first stop and trip duration being 15-20 minutes.

Using tickets between different trains

Tickets are interchangeable between the two types of trains so you can use tickets issued by the railways or use the Oyster Cards, Travelcards and other fare payment options you use on the London Underground and buses.

This makes things very complicated choosing whether you buy train tickets from the national railways or use Oyster Cards or Travelcards like you use on the London Underground, (see the discussion below).

If you have an Oyster Card, the default transport pass in London, you can use that to pay for the fare to Watford Junction.

If you have a Travelcard it is very unlikely you have bought a Travelcard to include the Watford Junction travel zone, the majority of leisure visitors will only have a zone 1-2 Travelcard.

London fare payments - Oyster Card, Travelcards or contactless cards? - full details

As said in the introduction you can either buy separate train tickets for your journey between Euston and Watford Junction or you can use Oyster Cards or credit/debit cards that support contactless payment - which many people will be using for their travel within London.

Cheapest or easiest rail fare from Euston to Watford and Harry Potter Studio?

It can be complex which option is best for you. If you are comfortable with understanding the comparisons between Oyster and national rail tickets you will be able to make the right choice for your needs.

However, as we note below, the simplest option as a visitor might be to bypass Oyster and just buy simple Travelcards for an additional cost of 60p per person for a return ticket.

Free travel for kids under 11

On the London Underground, London Overground and London's red buses, kids under 11 travel free without a ticket. On the national railways only kids under 5 travel free.

With both London Overground and Midland trains of the national railways both running along the same track an exception has been made that kids under 11 can travel free on Midland trains between Euston and Watford Junction only.

Midland trains or the London overground trains - Midland trains are faster

Whilst you can use either the London overground trains or the Midland trains, the Midland trains are much faster than the London overground trains that stop at every station between Euston and Watford Junction.

You can use either railway tickets or London public transport tickets like Oyster on both trains. The key point for those travelling to Watford Junction is that you can use Oyster cards and Contactless cards on the fast Midland trains.

Oyster Cards generally offer the cheapest train fares when in London, however as Watford Junction is on the farthest edge of London for Oyster use, you will find they are a little more complicated to use for the Warner Brothers Studio.

A simple option would be to pay a tiny premium over the cost of two single Oyster trips (there and back) and buy a return ticket on the railway. This return ticket will cost £13.00 off-peak (against £12.40 for Oyster off-peak return - see above) which is anytime at weekends and after 9am Monday-Fridays.

If you already have an Oyster Card you can of course use this and save a small amount of money, but you will need to swipe out of one system at Euston and enter the next within 15-30 minutes to stay within one fare.

For the visitor to London, the train fare is far simpler to use at a tiny additional cost.
