Here is a video my supervisor took. Vibration recording data used for the construction of some new alignment. We needed our top speed with 4 cars at grade. Only place we have that is down the middle of a busy road where we are in street mode allowing only 35 mph +2. Cops blocked roads, I had permission to bypass all stop signals. Also had to break the seals on the ATP BypAss and Speed Restiction bypass otherwise there is no way to achieve the speed. The beeping is the cut bypasses. Please enjoy.
