I love to travel coast-to-coast, as I live in Oregon and I have family in Chicago and New England. That gives me three full days to appreciate the scenery and to occupy myself. While I am generally a sociable person, when traveling alone I regard the three day trip as "Me Time" and don't go out of my way to make conversation. I always bring a hand project (crocheted potholders or a small knitting project), and a library book loaded on my iPad. Back when I was a working nonprofit director, I brought my work laptop and some hours of video clips for which I needed to write a script. Of course, I used headphones so as not to disturb my neighbors. That project occupied my spare time for the entire eastbound journey! Looking out the window occupies a large percentage of the time, whether my hands are busy or just my thoughts!
I'm a tea drinker, so I have found a small hot pot that uses only ~500 Watts. It doesn't boil the super very fast, but it has never blown a fuse, either. This allows me to make a cup of *good* tea in my own thermal mug whenever I want.
I am not used to sitting around at home, so I walk the train and take walks at the "fresh air" stops. It only takes a moment to move past the smokers so I can stretch my legs. I try to not get too far from an open door, unless it's a service stop and plenty of time till scheduled departure. Fun story: I live in a cold, snowy place, so I travel prepared for real weather. One January I was bundled up and walking vigorously up and down the platform at Shelby, with ten minutes left to go, when I noticed I was the last one on the platform. The attendants were waiting by several open doors, and they looked cold. I asked one if they were there just for me, and she admitted that if I got back on the train, they could all get back inside too. I got back on. We sat there for ten more minutes, and left right on schedule.
Just a note: I have not traveled since the pandemic started, and I won't until it's over. All my stories are from a time when we did not need to take any precautions.
