Introduction
This document was produced for the specification and harmonization of a specific set of ERTMS trackside
boards to support ETCS and GSM-R operations.
In EN 16494:2015, ETCS and electrification trackside boards were harmonized and these were specified
in a square format only.
In this version of the document, the following changes were made:
— Clarification of Scope to exclude mobile, backlit and temporary signs;
— Dimensional corrections to the ETCS Stop Marker and ETCS Location Marker;
— New trackside boards were introduced (traction system 25 kV, 15 kV, 3000 V, 1500 V and 750 V,
audible warning device, safe stopping area, non-stopping area, inhibition of magnetic shoe brake,
inhibition of eddy current brake, inhibition of regenerative brake, close air-conditioning, open air-
conditioning, and level crossing marker);
— An option for diamond-shaped trackside boards (electrification MBs only);
— Clarification to existing maintenance requirements;
— Revision of the options for standard dimensions;
This document contains colour images for indicational purposes only.
