The metro line A between Náměstí míru and Dejvická was out of service for about an hour. The cause was a fault in the overhead line.

According to the transport company, the metro did not run on Tuesday from 5:02 to 6:20. Alternative bus transport was provided by extending lines 107, 147 in the Dejvická-Staroměstská section.

Due to a technical malfunction of the signalling equipment, the operation between Skalka and Hostivař Depot was also interrupted for half an hour.
