I guess you are saying the rails are more isolated from the tunnel that they used to be?
How on earth do train drivers deal with the noise - do they wear ear defenders? It must cause permanent hearing loss and/or psychological impact.

do they wear ear defenders?
Yes, or at least they are provided with them by TfL. ASLEF/TfL have been having discussions about the long term implications, what can be done etc.

Yep! And the ever growing need for reliability means the use of modern track forms which are naturally less resilient [than timber sleepers which “absorb a lot of energy”.
Keeping trains running (track availability perspective), keeping vibrations out of basement developments… comes at a cost.

Okay. Blame basement developments and homeowners suddenly becoming vocal about ground borne vibrations.
In the past 20years; not the 1900s.
People dig down to build a cinema room, don’t enjoy the ground borne vibrations from the Tube.
Complain and instruct expensive lawyers.
TfL/LU come up with a solution to reduce these vibrations. Except energy cannot be created nor destroyed so shall still manifest… in the form of carriage noise.
There’s a lot more to it than that, but that’s the crux.
