Transport Prague testing holograms in the metro In Prague’s metro on Line A, new light effects have sparked discussions among passengers.

This innovation was not announced beforehand and was first noticed on the Line A.

It looks like that synchronized LED panels have been installed in the tunnel. They switch on when the train travels at a speed of at least 40 km/h.

Daniel Šabik, the official representative of the Transport Company of Prague, confirmed that the system has been adjusted and tested for the last few weeks.

However, he did not specify its intended purpose. He mentioned that the company will soon release a press statement with all the details.
