Preparations for the winter period in the metro begin in mid-May.
It is getting colder in Moscow: the average daily temperature is gradually dropping, and heating is turned on in all residential buildings and social institutions.
Despite the fact that the calendar winter will come in almost a month and a half, city services are actively preparing for the cold season. This is a hot season not only for specialists housing and communal servicesand road workers, but also for the metropolitan subway. Read more about how the Moscow Metro prepares for the winter period in this mos.ru article.
The metro conducts large-scale preparatory events annually and, most importantly, does it in advance. Work begins immediately after the previous heating season – from mid-May.
The main element of the heat supply system infrastructure is heat points. It is here that heating comes from the city, and only from here hot water is distributed throughout the station.
“We have 270 such points in total. Today they have all been checked, the necessary maintenance work has been done, revisions have been carried out, and we are ready to turn them on in the winter,” said Dmitry Doschatov. Heating in the subway is planned to be turned on as the temperature drops.
There are many different sensors inside the substation. They control circulation pumps, pipe pressure and, of course, water temperature. The colder it is outside, the hotter the water comes to heating points. Its average temperature is about 100 degrees. The heat point employees emphasized that the system works without incidents – all thanks to timely diagnostics and maintenance.
However, heating alone is not enough. In addition to launching the main systems, the metro is installing additional doors in the lobbies and preparing thermal curtains. All work is carried out at night so as not to inconvenience passengers.
In the metropolitan subway, more than 850 air-thermal curtains of two types are in operation – water and electric. Some carry out heating using hot water, others using thermal elements. The curtains are located at the entrances and exits at all stations, most often in the door vestibules. Heat exchangers that provide air heating are cleaned by specialists by rinsing with powerful pressures of water, and repaired, if necessary. Electric ones are blown by special compressors.
To take care not only of comfort, but also of the safety of citizens, special awnings are installed in the metro and a staircase heating system is turned on. Visitors can no longer be afraid of slippery steps.
“All flights of stairs are equipped with a water or electric heating system. The system is arranged as follows: under each granite step, pipes are laid with a length slightly less than the step. They are placed in a reinforced concrete block and poured with concrete, after which they form a single whole with the step. The temperature on the surface of the steps ensures the rapid melting of snow and, therefore, the safety of passengers when descending into the metro. In addition, we have equipped a lot of our exits with awnings, which prevent the penetration of moisture, rain and snow onto the flights of stairs, ”stressed Dmitry Doschatov.
The subway also continues to comply with all measures aimed at combating the spread of COVID-19. These are enhanced disinfection of the passenger area and rolling stock, the use of sanitizers, mandatory glove and mask regime and markings to maintain social distance.
