How will noise and vibration impacts be mitigated throughout the corridor?

Vibration mitigation measures will include installation of concrete floating slabs under the track on a section of Cedar Street in St. Paul to isolate vibration away from buildings. Track crossovers will be relocated in a few places to where they will not affect noise and vibration sensitive or historic buildings. A crossover is a track structure that allows continuous passage for trains between two nearby and generally parallel tracks.

In some locations, Metro Transit will modify its practice of activating train horns each time trains meet at grade crossings. Resilient track fasteners will be installed in locations where several sensitive laboratories are located. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
