The next figure show the graphic obtained at the time the train was passing over the bridge. <u>'''This graphic can be shown in real time while train is passing over the bridge'''</u>. The data can be also captured for further processing. The graphic represents the relative position of the top of the viaduct over the ground. Yes, the structure moves 2mm, will you take the next high speed train? Do not worry, this is normal and you do not have to worry about it, this vibration response has a normal profile.

The advantage of this kind of measurements is that tdepending depending on the vibration wave profile engineers can detect structure problems, in the same way a doctor can check if your hearth is OK by lookintg at an EKG.<br>
