Another thing I didn't know about train travel is the immense difference in timing. There is no security to clear and you don't check your bags. No one cares how many liquids you have in your bags or if you're carrying a swiss army knife. You don't board until a few minutes before the train actually leaves, much like a subway, but you have to schlep your bags. But, I found out, last summer. That a red cap guy is your friend. If you sit in business or first, you have access to these guys and for tips, they'll take your bags and get you on the train early. Who knew? I know I'm rambling, but it's all so new and I'm super proud of myself for figuring it all out.
