So far, the "noisy" issue of Fastrack has been mostly subjective...what I would LOVE to see is a more scientific appraisal - wouldn't it be great to get an actual decibel comparison of Fastrack with other track systems? Set them up, side by side, on the SAME surface, with the SAME loco pulling the SAME consist, running at the SAME speed, and take readings with the SAME instrument. That, to me, would be hard evidence.
But even so, some might actually prefer the louder noise because they would associate it with their memories of running trains in their youth; but then we could all make an informed decision and go from there.
For the record, until scientifically proven otherwise, I share the same feelings of Amtrak Jack and Professor Feinberg...it's a little too noisy for me.
