In addition to the problems related to working around utilities, subways built with cut and cover create a lot of street level noise when operating. Also, buildings vibrate every time a train runs by. Bored subways are imperceptible from above ground.

Not entirely true - the Crossrail in London goes under the Barbican arts centre, and that section of the track has special floating tracks to reduce noise and vibrations:
