LED Intermittent Railroad Crossing Sign

Intermittent railroad crossing signs are used to indicate that certain manoeuvres are allowed or forbidden when a train is travelling in an intersection or at a level crossing. They are highly visible and can be used to forbid manoeuvres in certain situations and can therefore ensure optimal traffic flow and direct road users during the passing of trains through simple and easy-to-read messages.


These signs are the most readable on the market because they are built with high-quality components such as LEDs specially designed for road traffic and a unique constant current modular power system that eliminates flickering.

Orange Traffic’s advance lane control signs also enable energy cost savings because they consume up to 90% less electricity than conventional fibre optic signs. Furthermore, their components are designed to facilitate installation, maintenance and upgrading and therefore lower operating costs. Finally, it is also possible to reuse the enclosure and wiring and replace only the front (LED) panel.

The wiring may be installed in the panel itself or consolidated with other power supplies in a more accessible area to minimize traffic disturbances during maintenance operations.

Orange Traffic offers an array of standard LED panels and several messages can be combined in a single panel. However, thanks to their modular design, these panels are easily adaptable to your requirements, and Orange Traffic is also able to design special or oversized panels. Feel free to inform us about your specific needs.
