BART is finally making a big effort to lessen the ear-pinching screeching on the tracks. I often see senior citizens with hearing aids, covering their ears in agony, or kids screaming to express their misery from the high-pitched and rough grinding of the train tracks. Residences along BART tracks will greatly appreciate this too.
Funny that right after this article was written, I experienced my worst track screeching to date. This morning, the screeching in the transbay tube was bad enough that I felt a vibrating pulse from my eardrum which felt like it shot up to my brain. Time for an improvement for sure!
