Summary

The goal of the leaflet is to specify the requirements for an automatic warning system.

Such a system aims at:

automatic warning of approaching rail vehicles in adequate time, with a high degree of safety, for staff working on or near tracks,

reduction of the staff needed for track-gang warning.

The leaflet is based on Report, Part 1, of the ORE1 A 124 Specialists Committee.

The system consists in an announcement part and a warning part, so designed that each part can operate separately.

The system is specified for operation till 200 km/h.

It is based on a radio transmission in the 160 MHz and 460 MHz frequency ranges.
