Do you like the style of the new departure boards in Karlsruhe? Well, they run Windows and a browser, and so I set out to clone them in pure handwritten HTML/CSS/JS. Simply enter any stop name in the world, and departures will appear just as in the original (some features disabled for technical reasons)!
On the backend side, most work is delegated to the amazing Transitous API, however, another, self-cooked API provides the line shapes and colors, by quering a CC0 database.
