I personally have lived in the basement at
81 Spadina road, which lies directly above the N-S Spadina station. Considering it is a station, the vibrations were quite strong and had woken me up several times. There was screeching from the tracks that could be heard from vents in the roadway through my closed window as well. Of course, there was also considerable traffic noise considering my ground-level window faced the street; and I had probably been woken up more times by
drunk people shouting outside the station than the subway itself.
Were vibrations keeping me up every night? No. Is it a valid concern? Definitely.
This isn't a nail in the coffin for future cut-and-cover. But it's important to realize that other people may have had different experiences than you and are not necessarily pushing some narrative or bias. It's more constructive to talk about concerns like that by acknowledging them and assessing them instead of acting like they don't exist.
