Hm. There's something strange about this, but I won't get into it. I couldn't get to the thick of it, anyway. Edit: In case you don't think the above is one number:
I came across a picture of a train numbered 607, yesterday. I can't actually remember what we used for 607... maybe just a screenshot with me in it? Transparency! I tried to find out what this is about exactly but it's getting late, and I would prefer moving on. It appears to be about renewable energy, though. The header on the homepage says the following: Computational materials sciences for efficient water splitting with nanocrystals from abundant elementsEdit: Huh, wasn't expecting that to be a link. Well, there you go, now if you want to do more research you don't need to google it.
Ah, that one is also nice! Going on the Arriva 607 shouldn't be too hard: it runs on the Arriva lines from Leeuwarden to Harlingen Haven, Stavoren, and Groningen -- and not yet from the other lines from Groningen, as far as I know.
It's been a while since anyone posted something from City-Data, I think. They're not amusing anymore since they fixed a bunch of the mistakes. This is an interesting one, though.
Wow, that one is very interesting indeed! Also interesting that (part of) that Zip code is called "Nuremberg", the English spelling of the German city of Nürnberg. This https://www.unitedstateszipcodes.org/18241/ website gives some very interesting data of the (residents of the) zip code. I would give some highlights, but literally almost everything is noteworthy.
