Transport for London (TfL) expects the effectiveness of these of rubber pads to last for at least ten years.

In some instances, TfL is installing these rubber pads on tighter curves than other networks. As a result, TfL continues to monitor the noise levels where they have been installed, in order to assess their condition.
