About 1 hour
About 1 hour 30 minutes from Waterloo Station.
30 to 40 minutes depending on route.
As there are no direct trains from Heathrow to London Waterloo, it's quicker to travel by underground from Heathrow on the Piccadilly Line to Leicester Square Underground Station and then change onto the Northern Line to London Waterloo Railway Station.
It depends entirely on traffic conditions but allow about 30 minutes.
London, Euston and London, Victoria both have underground stations on the Victoria Line.The journey time is about 8 minutes.
It is never certain because lately the trains have had many delays and cancellation's. It is best that you brace yourself for what ever the outcome as they may even be a delay on the track its self. Good luck!
