From March 1st 2020, Luxembourg will have free public transit throughout the country: you'll be able to travel on buses, trains, trams, and that one funicular railway without a ticket.

Schengen is a small town in Luxembourg, on the borders with France and Germany. But one of those borders is a little more complicated: the Mosel (or Moselle) river is a condominium, it belongs to both countries at the same time. And thus, so the bridges above it. REFERENCES: I'm not 100% happy with the research in this video, because it was put together quickly and, through necessity of language, from English-speaking secondary sources. However, Frank Jacobs in the New York Times on condominiums, talks about the history of the treaties: https://opinionator.blogs.nytimes.com/2012/01/23/the-worlds-most-exclusive-condominium/ and that's confirmed by a reference in Freshwater Boundaries Revisited: Recent Developments in International River Law by María Querol, which quotes Bernhardt's Encyclopedia of Public International Law, Vol 111, p465. Interestingly, the borders on Google Maps, Bing Maps and OpenStreetMap all take different (and sometimes nonsensical) twists and turns, so I've chosen to illustrate the simplest example.
