Is there a tool to see where I can go directly on a DB train without transfers?

Hi, I’m a pretty savvy traveler, but I cannot seem to find a tool that allows me to see what my options are for non-stop destinations from whatever.

The best I’ve found is hand jamming in destination onto the DB app and accidentally discovering train services to a city. For example, I was messing around and I saw I could take an overnight train from Stuttgart to Kiel without transfers.

I’ve also found the PDF downloadable from the DB website: [https://www.bahn.com/en/trains/intercity-eurocity](https://www.bahn.com/en/trains/intercity-eurocity) which has a messy inaccurate map of where I can go directly.

When I try to buy tickets, sometimes I can’t find destinations, and other times I can (e.g. Stuttgart to Zurich — I knew there was a non-stop train, but couldn’t find it on the website a few weeks ago, but I found just now).

If there a good way to check? Even if it isn’t the most formal of ways. Like the Airport Wikipedia Pages in English do an excellent job of showing you were you can fly, and finding the schedule is easy on some aviation websites or even on google.
