5 General
5.1 Overview
The following paragraphs provide a short guidance through the standard.
5.2 provides a procedure how to identify whether a ballastless track system design is novel and proposes
measures for implementation. For the acceptance of any track system, a Works Acceptance Plan should
summarize all steps and criteria for acceptance as described in 5.3 and 5.4.
Clause 6 defines the key acceptance criteria for ballastless track after completion. All criteria defined in
the following Clauses 7 and 8 aim to ensure that the overall criteria as defined in Clause 6 are met during
construction.
Clause 7 defines criteria for subsystems which are used in various ballastless track systems.
Clause 8 defines criteria for specific types of ballastless track systems.
5.2 Validation of fitness for construction of a novel ballastless track system design
The Common Safety Method for risk assessment, or an equivalent methodology, shall be used to
determine the significance of novel aspects of a proposed ballastless track system, (for example, see
informative Annex A).
To determine the significance of novel aspects of a proposed ballastless track system, a risk assessment
methodology (e.g. the Common Safety Method or an equivalent method) shall be used.
