I'm taking a trip from London to Amsterdam via the DutchFlyer. I'll need to take the train from London Liverpool to Harwich International. Part of the journey is by bus according to the NationalRail site due to engineering between Liverpool and Seven Sisters. Here's the warning. Do I still get on the train at Liverpool station or somewhere else? If I need to take a bus, will they have employees directing people? Do you think this will cause a significant delay in the overall journey time? I'm not too familiar with the train system, so thanks for the help.
