Proris – a new interlocking system for regional and moderate-traffic lines
Prolan started the Prolan Interlocking System (Proris)
development program in 2017. The system essentially
meets the Hungarian functional requirements, but it is also
flexibly applicable with regard to the demands of other railways.
A hybrid, (part relay, part electronic) system was developed
(Proris-H) before the full electronic version of the Proris
system (Proris-E).
