Visors for Railway Signalling Front shielding components for illuminated railway signals

NTET railway signalling visors are components made of Glass Fibre Reinforced Polyester Resin (G.F.R.P.), designed for installation on permanently illuminated railway signals.
The function of the visor is to reduce glare and unwanted signal visibility, improving the correct perception of the luminous message by the train driver, especially in conditions of strong ambient light.
The visors are developed in compliance with RFI railway technical specifications and are suitable for continuous outdoor use.

Technical Specifications – Railway Signalling Visors

Structure and Materials

The visors are made of Glass Fibre Reinforced Polyester Resin (G.F.R.P.), an insulating and resistant material suitable for use in railway infrastructures.
The structure ensures dimensional stability, resistance to atmospheric agents and the absence of corrosion phenomena.

Functionality

The visors are designed to limit the direct incidence of sunlight and ambient light on the railway signal, improving the readability of the luminous indication under all operating conditions.
Their use contributes to the correct interpretation of the signal by driving personnel.

Compliance

NTET visors are designed and manufactured in compliance with RFI railway technical specifications for signalling components.
The product is intended exclusively for use in railway systems.

Useful resources

Versatile Applications

NTET visors are used across the entire rail network, wherever it is necessary to ensure the correct readability of permanently-lit signals in any lighting condition.

  • Conventional and high-speed lines

    Installed on permanently-lit signals to reduce glare and the "phantom signal" effect caused by sunlight.

  • Stations and complex junctions

    Applied to station signals and yards with a high density of light sources, where clear message recognition by the driver is critical.

  • High-illumination environments

    Used in contexts with direct or reflected radiation, improving safe signal perception, in compliance with RFI specifications.
