Yeah, I used to like the sound of puffing steam locomotives at nite when I was a kid. Road noise(IMHO the closest to HSR noise in blight potential) is not like that - the more of it the more obnoxious and intrusive. And it is not a positive for property or resale values.

The higher speed of HSR is magnifying the noise beyond what is expected normally of trains and will just increase if you crank the speed even more. These people in France messed up - they look pretty sheepish in the video - and failed to think worst case scenario. When you are humble ordinary folk always think worst case scenario - don't believe the reassurances and nostrums. They found out the hard way. The elite don't have to worry about this so much as they keep things like HSR, freeways, homeless, etc., well removed from their enclaves. That's why there is no HSR at Lebec.

So my advice remains the same to the little people of California who have property(likely their most valuable possession)close to Jerry's Legacy: sell it now while they are still believing the reassurances and spin.
