SOUTH TUNNEL BORER OF METRO 4 ALREADY ARRIVED TO NÉPSZÍNHÁZ STREET – IT MAY REACH KELETI RAILWAY STATION BY MID JUNE

South TBM of metro 4 made it one week earlier than planned to the second last, Népszínház Street station. Instead of the previously predicted preparation of six weeks the tunnel builder plans only two to three weeks of maintenance period at the station, so at the end of April the tunnel borer may commence the works of the last section. If everything goes by the plans and BAMCO can keep up this pace, then the south TBM may reach the first section's temporary, Keleti pályaudvar end station even at the middle of June

The south TBM set off from Rákóczi Square station on 8th March and completed the 450 meters stretch to Népszínház Street in five weeks. Its north pair was launched a few days later. In contrast to Buda the Pest side is still very good, it is being built with a pace surpassing the expectations despite the fact that the soil conditions are much more various in this part, than that the tunnel builders were used to in Buda. Specialists do not expect major difficulties, albeit – as noted earlier by DBR – the tunnel borers leave the clayey soil over the section before the railway station. They will pass gavel stratum at some places over the last 150 m of the also 450 m stretch, which if hopefully would not result in slowdown, but will in any case require special preparatory works and higher attention.
