As a part of a comprehensive reconstruction on the new line, a modern truck will be built, there will be a complete electrical reconstruction, the safety equipement will be replaced, the train control system and conductor systems will be replaced, the passenger areas and the stations will be renovated. The renovation of the trains have already started. The first refurbished trains have been in operation since March of 2017.
During the development of the line it was required that once the works are finished, the trains will operate with an average speed of 80 km/h. The superstructure will be unified and it will be possible - based on the distribution of stress on the materials - to install 75 cm long fastenings according to the support width.
A complex machinery refurbishment will take place. Among others these include upgrading the basic safety services - as a part of this development a new fire protection system will be installed according to the latest regulations, a modern ventillation system will be built as well supplemented with a water mist fire protection network.
Almost 340 emergency call equipment will be available for the ridership. For supporting the works of the dispatchers both at the stations and in the central command 160 monitors and 500 IP camera will be installed thus in case of need these will help to intervene faster and more efficiently. Both the stations and the passanger areas will be refurbished.
One of the main goals of the architectural design was to keep the unique image of each stations, by using the same colours and by preserving the pieces of art located there.
It is exceptionally important to create and maintain the accessability to everyone, to help the travel and orientation of the disabled passangers. These include tactile paving for the visually impaired, elevators in 12 stations for wheelchair users.
Besides renovating and changing the existing escalators, new ones will be installed to ensure the convenient travel. The regular lighting system will be replaced by LED ones.
300 centrally controlled clocks, 180 visual signs as well as 2060 pieces of loudspeakers will help to guide and assist the passangers. During the reconstruction circa 32.000 m² of floor paving will be replaced.
A data transfer network with 10 Gbit/s bandwidth will be installed for the communication and maintenance of the metro line. Since 1990 subway cars with one driver, guided by an automated line control system (AVR) operate the area. During the reconstruction this AVR system will be modernized as well.
