U1: continuous operation since the start of service on Friday, 29 November

Update 29.11.2024, 08:30 hrs: After the fire on a train on the U1 line last week, Wiener Linien was able to reopen the closed route. Since the start of operations on Friday 29 November, the U1 has been running again on its entire route between Leopoldau and Oberlaa. 300 employees worked around the clock to repair the severely damaged line, carry out safety checks and complete the necessary technical tests.

Damage was repaired in record time

We checked the structure for damage as soon as the clean-up work was complete. We then carried out repairs to the infrastructure: We not only had to lay 50 metres of track, but also several kilometres of cable. Once the basic technical infrastructure had been restored, tests were carried out to ensure safe railway operations. A track measuring carriage was then deployed - just like after the flood work. Finally, final test runs were carried out and all affected stations were thoroughly cleaned again. Thanks to the extraordinary efforts of around 300 employees, who worked around the clock, the line was reopened in record time.

A big thank you to the Wiener Linien team
