Thanks Andi and Freddie,

My DH is saying the same as that's the way he would travel from London to Heathrow when he has been there for business.

Are these trains more like subways, or are they like regular trains? Is there space for luggage? Unfortunately, we are not traveling light ( we are on the QM2 and they have 3 formal nights!!!!)

Thanks for any other clarification you can offer.
