This document describes the different modes of operation and the classification of machine types.

This document covers machines fitted with rail wheels that are used for the construction, maintenance, inspection, repair and renewal of railway infrastructure. These include:

— on-track machines (OTMs), which are specially designed for construction and maintenance of the track and infrastructure;

— infrastructure inspection vehicles, which are utilised to monitor the condition of the infrastructure;
