Keeping busy on a train depends on the length of your journey and whether you prefer productivity or relaxation. For a long-distance trip, downloading movies or podcasts beforehand is a classic strategy, especially since Wi-Fi can be spotty in remote areas. Many travelers use the uninterrupted time to read a book or catch up on journaling, letting the rhythmic motion of the train enhance their focus. If you're feeling creative, sketching or photography through the window is a great way to document the changing landscapes. For the more productive, "offline" tasks like organizing your photo library or cleaning out your email inbox can be very satisfying. If you're traveling with others, a simple deck of cards or a travel board game can provide hours of entertainment. Finally, don't forget the simplest pleasure of train travel: mindful window-gazing, which allows you to appreciate the scenery in a way that air or car travel simply doesn't permit.
