Pros: I could relax for the duration. Unlike an airport, there were no obvious screenings. Cons: The food offerings were too limited. Tips: The train gets cool at night. I'm glad I brought a shawl to use as a blanket plus a warm jacket that could double as a pillow. My bandana worked as a mask and was large enough to pull up onto my forehead at night to cover my eyes, nose and mouth!
