A temporary detour was built at Kőbánya-Kispest metro station

An important and spectacular part of the renovation of metro line M3 is the reconstruction of the tracks of the southern section. During the organization of the work the train traffic always has priority, therefore a new temporary detour was built at Kőbánya-Kispest metro station in order to ensure the replacement of the trains.

Unloading the rails

In a previous year's report, we have already described how - in line with the renewal of the entire track section - the delivery of each 108-meter long rail in the area under construction is done, where they are placed, how they are welded, and finally, by what means their surface is grinded to the right condition.


The left track was renewed on the southern section of metro line M3

Aligning with the schedule, the left track, which was previously demolished and then rebuilt, is slowly being completed on the southern section of metro line M3.

An important condition of the reconstruction was that - just like in the northern section - only one of the tracks can be demolished at the same time, because on the other one the transport of the subway cars must remain undisturbed as well as the transport of the different materials also happen there. As we reported earlier, track upgrading can only be performed during the stress relief of the entire track section, generally between 6 AM and 7 PM hours.
