What AŽD Praha does

AŽD Praha s.r.o. is a privately held Czech supplier of railway signalling, control, telecommunication, and safety systems, headquartered in Prague and operating across more than 20 countries through wholly-owned subsidiaries in Slovakia, Poland, Bosnia and Herzegovina, Serbia, Croatia, Turkey, and Bulgaria. The company, founded in 1954 (predecessor organizations) and privatized in 1993, employs over 1,700 people and runs in-house manufacturing in Brno and Olomouc, an 8,248 m² logistics centre with 26,000 SKUs, and assembly facilities in Kolín and Olomouc. Its product portfolio spans four interlocking platforms — StationSWing (ESA 51/44/11M electronic interlockings), TrafficSWing (GTN with ANP RJ automatic route setting, DOZ-1 remote control), TrainSWing/RailSWing ERTMS/ETCS infrastructure (REA-11 radio block centre, eurobalises, LEUs, GSM-R gateways), and GateSWing level crossing protection — supplemented by DiagSWing diagnostic systems, PointSWing point machines, FieldSWing LED signals, metro automation (LZA, ACBM3, SOP-2P), and road traffic controllers (FlowSWing).

The business model is B2G/B2B project delivery: complete turnkey execution from design and in-house manufacturing through installation, commissioning, and warranty service for state-owned railway infrastructure managers (Správa železnic, České dráhy, Dopravní podnik Praha, HŽ Infrastruktura, PKP PLK) and metro operators, with secondary revenue from road infrastructure companies (Metrostav, Skanska, PSVS, SSŽ) and ancillary electron-microscope system integration (Nanotech). Revenue streams combine one-time project delivery, hardware sales from proprietary components, maintenance and service contracts, engineering design, and logistics supply — with no public pricing and project-based contract values reaching tens of millions of EUR per tender. Distribution is direct enterprise sales via national subsidiaries, complemented by industry events (InnoTrans, TRAKO, Rail Business Days), a quarterly magazine (Reportér), and a training partnership with Signal Projekt.

Certification under ISO 9001/14001/45001/27001, EN 15085-2, EN ISO 3834-2, and SIL 4 (ESA 11), combined with permanent membership in UNIFE and active participation in the UNISIG ERTMS consortium, underpins regulatory positioning for European interoperability tenders.
