As soon as prepared, engineers started lifting the construction greater than 5 metres off the bottom utilizing hydraulic presses. That step needed to be accomplished slowly to maintain the bridge steady.

On Sunday morning, the principle transfer started. As a substitute of cranes, ÖBB used self-propelled modular transporters (SPMTs), that are heavy-duty platforms usually seen in industrial websites.
In whole, 12 items have been used, carrying 56 axles and 112 wheels. They moved at round 1-2 km/h, giving exact management because the bridge rolled into place over Hallerstraße.
The construction was additionally turned roughly 90 levels earlier than being lowered onto its new helps.
Engineers mentioned the tactic was safer and extra correct than lifting the bridge with cranes, particularly in a dense city space.
Work on the mission remains to be underway. Over the following few days groups will set up bearings, end the helps, match railway tools and put together the road for reopening.
