I'm thinking of taking this ride if I ever get across the pond. My research says that they have some sort of preclearance procedure for passport control, but you're still subject to customs inspection when you get off on the far end. What is that like currently? I'm hearing all kinds of horror stories about what might happen in April with customs lines if the UK and EU don't have some sort of Brexit agreement. Does anybody know how that might affect the procedures for the Eurostar?
