I love these futuristic-looking trams in Luxembourg. And they can even travel through the city without the overhead wires that most other trams require. Pretty cool! When the tram enters the city centre, it lowers its pantograph and continues on without any electrical connection. This works by having a supercapacitor mounted on the roof of the tram. These can charge much faster than a battery, but they only provide a small amount of power. So at every tram stop, there are these two plates that energise when a tram is detected. The tram then connects to these metal plates and charges the supercapacitor while passengers board at the stop. And that provides just enough power to the supercapacitor for the tram to continue on to the next station. Luxembourg chose this technology by the Spanish tram manufacturer CAF for aesthetic reasons, to maintain the beautiful historic look of the city centre, without a bunch of ugly overhead lines ruining the view. Now, if only they could care enough about aesthetics and historic preservation to get rid of the wide roads, oversized traffic lights, and other ugly car infrastructure that’s right next to the tram line. But hey, at least there aren’t two wires running over the tram tracks. What’s most amazing about Luxembourg though, is that all public transit, across the entire country, is completely free. If you want to see what it’s like to ride public transit in Luxembourg, then check out my new travel show Day Pass, where I explore Luxembourg exclusively by public transit.
