Railway signaling

Modern, efficient and safe rail networks attract more passengers. Modern railway signaling systems rely on new tools and platforms which combine both hardware and software solutions.

We make your networks safer, more reliable and more durable – hence more attractive to the general public who uses them.

We are also experts at managing the obsolescence of your systems which is all important in an ever evolving regulatory climate.

Digitalization of railway signaling

Meet the BGS4SIL Series, our SIL4-certified hardware and software platform for developing your digital railway safety applications

Signaling must take into account cost, capacity, interoperability and ease of deployment factors while guaranteeing safety and reliability. Digitization and the use of generic equipment are important means for making the renovation or creation of new railway lines viable.
