I also wanted to add some perspective about Andrew being on the train that I think gets overlooked. I’ve spent time in Germany, and I had serious culture shock when I saw four-year-olds taking themselves to kindergarten on public transport. This video explains what I mean really well:

So the fact that people think it’s “weird” for Andrew to have been on a train doesn’t seem odd to me at all. Even here in the UK, I’ll be going to the dentist during school or work hours and then go to the bus stop, and I see kids who are fifteen waiting with me. I always instinctively text my husband about it, and he always reassures me that it’s normal for England. I’m American, and I’ve been living in the UK for a decade, so it still surprises me—but to locals, it’s completely ordinary. That’s probably why no one thought to question Andrew being on a train by himself.
I also don’t think he was “looking for someone” at the station. I think he was simply taking in his surroundings. Personally, I’ve never been taught to read maps—born in the late ’80s, no proper geography classes—and I rely on MapQuest and Google Maps. Even now, navigating London without a maps app would leave me completely lost, despite having been there many times. I use it all the time just to make sense of my surroundings.
I think Andrew was probably doing the same—just trying to orient himself, not actively searching for anyone or anything.
