The purpose of this document is to describe the calculations of noise and vibration source levels to be included in the database for the web-based tool for track optimisation. Results for a range of abatement methods are also specified. These parameters and abatement methods are aligned with the work of Task T4.

Deliverable D4.1 presents the outcomes of Task 4.1 of the QuieterRail project, which focuses on defining representative Use Cases and associated optimisation criteria for the whole track system, considering noise, vibration, and life-cycle performance
