Paris and Berlin will even closer next year with the launch of high-speed rail service.
From as soon as December 2023, travellers could take a direct train from Paris to Berlin in just seven hours, according to French rail operator SNCF.
According to SNCF CEO Jean-Pierre Farandou, the route made sense, especially as long rail journeys appear to be rising in popularity.
"It makes sense because we see that people are accepting longer and longer journeys. There are really people who are willing to spend five hours, six hours, seven hours on a train," Farandou told AFP via Euronews.
SNCF and Deutsche Bahn, a German rail operator, currently run some high-speed train services between Paris and German cities like Frankfurt, Stuttgart and Mannheim.
