Starting from 1st of March 2020, Luxembourg abolished train, bus and tram fares for both, residents and tourists. alike, (with the exception of first-class train fares). Some European cities have previously introduced free public transport, but this makes Luxembourg the first country in the world to have a free public transit system, although you have to pay for first-class train tickets).
The government of Luxembourg took the decision mainly for environmental reasons in a move to get more cars off the road. Luxembourg has the highest number of cars per resident in the EU.
Well done, more countries should take similar action.
