Universal level crossing system SZP-1 is intended to protect traffic at cat. "A", "B" and "C" level crossings as well as it can be used to retrofit cat. "E" crossings.
SZP-1 is used on single-track and multi-track railway lines (electrified and non-electrified), where the maximum speed of trains does not exceed 160 km / h. The SZP-1 system is designed to support crossings covering a maximum of 4 tracks, and can also be used on crossings where an additional siding track is present.
The system may be related to or dependent on station equipment at a traffic station, based on applicable regulations.
