During the reconstruction of metro line M3, a new, modern track structure will be built. The transport of the railways requires precise and meticulous organization, since the 108-meter-long elements are carried to the destination at once. It is quite difficult to imagine a 108-meter long rail, for example, if it were to stand next to the Hungarian Parliament building, it would overtop that exactly 12 meters above the highest point.

From our last report you could find out how the deliveries in general are performed through the BKV Zrt. Kőér utca vehicle depot. In this article we follow a specific transport en route to the tunnel.

In one of our previous report we wrote about the transportation (in and out) of various construction materials and tools, equipmments, and bigger machines to the reconstruction sites of metro line M3 and how essential these tasks are. All these works are done via the Kőér utca vehicle depot.

As we previously reported, there are spectacular changes in numerous work processes affected by the reconstruction.

Implementation of these tasks require high level of work time, schedule. As a result of the construction materials, tools, equipments transported to the area, as well as the completion of the required work, significant progress can be noted in several places and phases of work.

As we previously reported the ÁDI (stationary dispatcher room) are those places what are structurally complete already in the northern section of the renewing metro line M3.

As we mentioned earlier the reconstruction of the metro line M3 does not stop during the summer break.

Professionals working on site perform their tasks in line with the tight schedule, resulting in spectacular changes in various locations.

The reconstruction of metro line M3 is the major project of Budapest since last year’s November. Organizing and executing the required works is a difficult and comlex logistical task, since the only permanent surface connection of the metro situated at the Kőér utca vehicle depot, what lies at the southern end of the 17 km long line.

In our last report the ongoing reconstruction works was the main topic, however as for novadays it can be stated that on the northern section the stationary dispatcher rooms (ÁDI) are in the most advanced state based on their completion. With the support of the other technical areas (such as the track-telecommunication rooms) linked to the central dispatchers, will be an essential part of the renewing control system of metro line M3.

In the reconstruction of metro line M3 - like every complex processes and procedures - certain order must set for the different workphases. Before the spectacular demolition and building, plans must be made by measuring and modelling the stations; these are also key factors for the whole project.

Since our last report many things happened in accordance with the reconstruction of metro line M3 both under and above ground. Thanks to the works of the experts on spot, the changes are more and more visible whether you look at the stations or the service areas.

Most of our news updates were about the reconstruction of the stations themselves, yet there are also works going on in the tunnel as well. Both the track and the tunnel developments are important parts of the general reconstruction of metro line M3, although less spectacular.

A couple of weeks ago on the 25th of May the General Assembly of Budapest voted in favour to make all 20 stations of metro line M3 accessible. On the 10th of May István Tarlós, Mayor of Budapest and Ágnes Kovács chairman of the National Federation of Disabled Persons’ Associations (MEOSZ) held a press conference where they signed an agreement of the accessibility of the metro line.

Structurally speaking, there are many examples across Europe for accessibility with incline elevators. These structures and their enviroment could hardly (or with great risks) be served with regular elevators. In Prague, Paris, London and Stockholm incline elevators are operating in different metro stations in order to maintain accessibility.

There are many enamel-made pieces of art on metro line M3 what are decorating the passenger areas since the nineties. An important part of the reconstruction is to restore and renew these pictures.

As we previously reported demolitions were exchanged by reconstruction works in many areas of metro line M3; however plenty of these happened in those sections what won’t be visible for the ridership even after the works are finished, such as reshaping the service areas, replacing the public utilities.

As for every grand-scale reconstruction - just like the ongoing works at metro line M3 - besides the experts, specialized machines are needed to take part in the different phases of work.

During the works all the areas of metro line M3 will be renewed, meaning that currently the works are happening not just in the tunnel but in those areas as well what are resctricted to the ridership. There were many changes (regulational ones also) since the first subway cars put into operation back in the seventies. The service areas in the background will be refurbished according to the renewed directives.

As we previously reported, during the reconstruction of metro line M3 works both under and above the ground are underway.

Reconstructing the metro line is a special task since there is only one ground connection available (at Kőér utca vehicle depot) to move in and out all the machines, tools, materials and to transport the debris. When it is time for metro replacement buses to swap the subway cars, all the flat wagons begin their daily routine under the ground by transporting in the construction materials.

Underground works are going on with the same speed. Experts and various machines spectacularly reshaping both the image of the stations, the service areas and those places with the machinery equipment as well. But what about the works above ground in the meantime?

You can hardly compare the metro stations with their former self now that they are under reconstruction. Removal of cladding, reshaping the service areas put a really distinctive mark on the image of the stations. You could easily imagine yourself in a film set - if it wouldn’t be obvious where were the photos taken.

There are many areas in metro line M3 where even in its operational days only the experts and members of the maintenance staff are allowed to enter.

People tend to believe that those things they don’t see are non existent. However it is quite the opposite about the construction of metro line M3. Although little activites can be noted above ground, majority of the happenings take place under the ground.

People experience something of the M3 metro line reconstruction on a daily basis – mostly above ground. Besides replacement buses many situation which occur with a development this big.
