Installing the control system of the metro

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.

Modelling the metro

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.


After demolition comes the building

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.


Why is it necessary to close the whole section of metro line M3 after weekday’s peak times and at the weekends - during the other renovations scheduled to summer break also?

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. All machinery, tools and materials are transported inside from here on special railway cars (flat wagons) to the northern section under reconstruction and the materials, debris are also transported from the tunnel on this location. To reduce this logistic difficulty at Temesvári utca a new opening was created by dismounting the superstructure (previously reported HERE), but this cannot serve as an alternative route at all times, for example when the new rail parts are being delivered inside.
