My perspective is London where you do get basements rumble with the trains below, we did have Crossrail put in with a lot of disruption to existing infrastructure being more of a problem than the ground shaking to pieces. They did have a very large TBM and they also had to weave through and around a lot of other tunnels beneath the ground. A lot of lasers above ground made sure things did not subside, which was a bigger problem than the rumbling, which is a one time thing. With the aforementioned basement situation there is a rumble every few minutes.
