Several central stations on the Moscow metro's Red Line will be closed on Saturday to allow repair work to be carried out on the track, the subway said in a statement.
The Krasniye Vorota, Chistiye Prudy, Lubyanka, Okhotny Ryad, Biblioteka Imeni Lenina and Kropotkinskaya stations will be shut all day Saturday and will reopen Sunday at 5:30 a.m., the statement said.
In total, 1,000 maintenance staff will work to replace worn tracks and rails on a stretch of line covering 5 1/2 kilometers of track, the subway said. The work is being done on a Saturday to minimize inconvenience for passengers, it added.
The subway has sought to improve its infrastructure this year following a train derailment last July that resulted in the deaths of more than 20 people.
In all 100 kilometers of track will be replaced on the underground this year, the metro said in its statement.
