I'm sure someone has considered the issue that if MP wants to elevate the tracks for its four crossings, how does that affect its neighbors? meaning the station at University and crossing at Alma in Palo Alto and the Watkins crossing and Fair Oaks crossing and station in Atherton.

It's too bad that we have multiple systems for transit around the Bay -- BART, CalTrain, and light rail and all the bus systems.

I live very near the tracks, and cannot understand the concerns about noise due to elevation... the main noise concern is caused by the honking of the trains at the intersections, and grade separation was put an end to this phenomenal noise generation. The rumble of the train on the tracks is nothing compared to the mandatory alerts as the trains approach the crossings.

Thierry, I completely agree! Horn noise is the real issue which is why we should also be discussing implementing quiet zones.

Bob: none of the proposed grade separation alternatives including the one that would fully elevate tracks between Glenwood and Ravenswood would affect Palo Alto or Atherton. None build grade separations at Encinal, and all have graduated tracks that remain entirely within Menlo Park. Thanks for raising this concern.
