How long will it take on the tube from London Waterloo station to Euston station?

The London Underground (commonly known as the Tube) does not offer direct service between Waterloo station and Euston station. You will need to change trains at least once along the way. The fastest and most convenient option is to take the Jubilee Line from Waterloo to Green Park, then change to the Victoria Line towards Walthamstow Central and get off at Euston station. This journey should take approximately 15-20 minutes, depending on the frequency of the trains and possible delays.
