Nauseas in Transportation

Hi ladies, I will be traveling to the UK from the USA next week. I am early in my pregnancy so really nauseas. I have to travel for work from London to Farnborough, in your opinion which method will make me less nauseas. Traveling via train or car ride? I think I get extra nauseas in the car but don’t know what it will be like with a train. How do you mamas do it there? And any tips? Should I close my eyes the whole time. Thanks!
