Rail grinding

One of the most important parts of the renovation of metro line M3 is reconstruction of the track itself. We have already written about the transport of tracks that are longer than the height of the Parliament building, and we have also published a video report, as well as have mentioned how carefully and well-organized the transport equipment and the professionals must be working on it. After the delivery has been completed, the rails are welded together to form a single rail track - this is also a spectacular process that we have previously reported.

Summary of 2018

Since the beginning of the reconstruction of metro line M3 in the 6th of November 2017, we submitted multiple reports about the ongoing works, such as the removal and supply of the construction materials, the various processes of both above and below the ground. We also mentioned those special machines what have been modified to tunnel works, and wrote about the accessibility of the stations, and in relation with that, the foreign examples, or the 3D modelling of the current project.

Developments about the reconstruction in November

In our usual monthly report, we browse a number of important and spectacular parts of the workflow for the reconstruction of metro line M3, which is illustrated by the attached gallery - the pictures were taken at the beginning of November, so they do not represent the current state.

One of the most interesting phases of the underground works on the track sections is grinding, which has been implemented with one of the most modern Speno rail grinders in the modernization of the northern section of the M3 metro line.

Expected changes

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.
