Operation at Wels Central Station
In May of this year, Bahnbau Wels handled a complex construction site next to the company's headquarters at the main railway station in Wels in partnership with the specialist departments of ÖBB.
The project was carried out in several, extremely complex and coordinated construction phases on behalf of ÖBB-Infrastruktur AG. The construction project comprised the removal of the track ballast bed including soil replacement and the renewal of track and switch systems. The work was done in the area of the heavily trafficked western railway line on tracks 1 and 2 at Wels Central Station while maintaining railway operations on at least one track.
The construction teams of the commercial track construction division at Bahnbau Wels conducted the work of replacing the soil and placing the new base ballast for the later laying of the switches and tracks. Around 9,000 tonnes of ballast and subgrade were removed conventionally with the two-way excavators of Bahnbau Wels and around 5,000 tonnes of 70/150 gravel and 2,500 tonnes of track ballast were re-laid.
The re-laying of thirteen switches, two crossings and about 300 metres of track was carried out by ÖBB's 201 construction train with the support of the Mechanised Track Construction department of Bahnbau Wels. Bahnbau Wels’ Kirow crane was used to manipulate the track and switch parts. The tamping work was also done by BBW machines, including the new Universal Tamper 4.0 tamping machine. The final step was the grinding of new rails by Bahnbau Wels’ oscillating rail grinding machine.
“This construction site was an absolute BBW home game and once again confirmed the good cooperation with our proven contractor Bahnbau Wels," Andreas Zallinger from 201 construction train emphasised the perfect interaction between ÖBB and Bahnbau Wels for this contract.
