Railway Applications — Principles of train detection for operations and services

Scope

The scope of this document is to provide generic principles of train detection, related operation management principles, and to show the link between them. It provides non-technical guidance for supporting the choice of a suitable train detection method relating to railway operation.
It includes:

the generic principles of train detection.
a list of operational and environmental conditions affecting train detection.
a list of all train detection methods
possible selection criteria of each type of train detection.
the impact of each train detection method on operational requirements.
related operational management principles, for deficiencies and failures in each train detection method in operation.

It excludes:

any technical requirements of specific train detection devices which are in the scope of IEC/TC9.
technical aspects of any future train detection technology covered in IEC/TC9.
