Overpass works

Attention, loud noise. At the begging you can hear workers fixing high voltage lines over train tracks, talking and listening to the radio. They are working on a platform and the driver signals with a horn when they move to the next section. The tracks are located on a viaduct that is also under repair. Around 1:30 mark the worker starts sanding the base of the viaduct. Even though I was almost a hundred meters away, the sound of the sanding was deafening and drowning the heavy traffic moving below the viaduct. (roland r-07)
