A projekt az Európai Unió támogatásával, a Kohéziós Alap társfinanszírozásával valósul meg.

OPEN DAY AT THE TÉTÉNYI ÚT STATION OF METRO LINE 4


18 february 2013

The M4 Project has joined the initiative of the National Development Agency entitled “Open Day of EU Development Projects”. In the framework of the event, the almost complete Tétényi út Station will be opened to the public at large.

During the Open Day, visitors who have registered previously will be able to look around behind the coulisses of the metro construction project with the help of professional guides at the Tétényi út station, which has reached the highest level of completeness among the stations. The reason why this station was chosen is that visitors will be able to see here conditions close to those at the time the Test in Traffic Operation is planned to begin in a year’s time – Swietelsky Magyarország Kft. is about to complete the fit-out of the station.

IMPORTANT NOTICE

People are allowed to enter the worksite at their own responsibility. No one under 14 years of age is allowed in the worksite, and under-eighteens must be accompanied by adults. Work-safety helmets will be provided, but thick-sole hiking shoes as a minimum must be worn; people wearing thin-sole shoes will not be allowed to enter.

RELATED BACKGROUND INFORMATION:

The M4 Project is the most significant, largest infrastructural, transport development project in Budapest, employing the largest number of people, which is funded up to 180 billion forints by the European Union from the Cohesion Fund. After its approaching handover in the first half of 2014, the new line with automatic trains will connect South Buda and North Pest. With a 90-second allowable gap between trains in peak hours, it will take a quarter of an hour to carry passengers from Kelenföld to Baross tér, avoiding congested surface traffic. The project, which has now reached 80% completion, has had phases in which it provided employment for some 5000 people.

The new Budapest metro line is 7.5 km long, in other words the two shields had to drive through 15 km of ground under the city. The alignment is relatively close to the surface, but, approaching the Danube, it goes deeper from both sides: reaching 34-36 meters depth at Szent Gellért tér and Fővám Tér stations, i.e. a ten-storey block of flats would easily fit in these stations.

The cutter heads of TBM shields were above 6 metres in diameter, and the shields themselves with their back-up equipment were some 100 metres long. The shields achieved, on average, 15 metres progress daily, but there were times on the Pest side when it managed to put 31 rings in place, that is made 45 metres progress in a single day. Once, during the drive under the Danube, clay clotted on to one of the cutter heads, which had to be cleaned in caisson under the river by specially trained experts.

Fair-face concrete surfaces will be characteristic of all stations. The essence of this now widespread architectural design is that a significant part of the surfaces retain their natural concrete colour, which will then be lighted in various and variable colours at the end of the construction, lending unique features to the stations. The entire line is characterized by its unique architecture: Fővám tér station for example has already received several important international architectural prizes already before opening.

Though the platforms of the stations were designed to accord with the 80-metre length of the trains, the river and the buildings of the universities on the banks determined the geometry of the design. Of the Szent Gellért tér and Fővám tér stations, only about 40 metres could be built by usual methods, the platforms conforming to the length of the trains and reaching under the Danube had to be mined, moreover freezing by liquid nitrogen had to be applied to ensure maximum safety.

The depot of the metro line is also special with its 8-storey ultramodern tower and the Control Centre on its top floor, from where the traffic and service of the entire line will be directed. The ground space of the depot buildings is near 20,000 sq m. Though accompanied by train attendants in the initial period, the trains will run in fully automated mode, which is the most predictable, fastest and safest mode of train control according to international experience.

Aside from the vicinity of the river, the exclusion of water inflow possibilities, a particular challenge was the protection of thermal springs around St. Gellért Hill. Metro Line 4 is a green investment not only in respect of image; environment protection has been a major consideration throughout the project, from the initial earth work, too. Builders planted five times as many trees as they had to cut or replant in the areas of the stations, and took especial care to protect the built environment, old buildings.

Metro Line 4 will be fully accessible; the design of its subways and platforms is such that they will be equally accessible to all. The orientation of the blind and dim-sighted will be solved by floor signs and audio equipment, and those hard of hearing will be aided by special visual display equipment. Aside from the many escalators, lifts will be available at all stations for the disabled with wheelchairs and mothers with prams.

In the framework of the Open Day of EU Development Projects on 2 March 2013, BKK and BKV will show the Tétényi út station of Metro Line 4 to the public at large. This is the station which has reached the highest level of completion; the public will therefore now be able to see what they will experience as passengers in a little more than a year’s time. Due to its special cupola structure, the architectural concept of the entire line, that natural light should find its way right down to the platforms, will prevail at Tétényi út station, as well. The designers implemented scores of ideas and solutions to make travel by metro be a realistic alternative to travel by car. These solutions, the huge internal spaces and natural light, will decrease the sense of being closed in and increase their comfort.
