Track maintenance on active rail lines remains one of the highest-risk operations in the railway industry. Reaction-time gap between a lookout's warning and a train approaching at line speed is the leading cause of fatal incidents on the track.

CTRL+N develops real-time safety systems that protect track workers during maintenance operations on active railways. Our flagship product, SPAS, automatically detects approaching trains and alerts the entire crew through simultaneous vibration, sound, and visual warnings — delivering alerts in under 0.5 seconds, compared to 1–3 seconds for human reaction.

**What we deliver:**
- Workforce management — activity and work profile tracking (work/rest states, tool use: hammer, broom, etc.) for subsequent planned vs. actual work analysis according to assigned tasks
- 10 cm UWB positioning precision — centimeter-level accuracy in all field conditions, indoors and outdoors
- Multi-channel alerts in <0.5 sec — warning reaches workers in noisy, low-visibility environments
- BLE mesh relaying — extends alert range by hopping through nearby team devices, reaching personnel beyond direct source coverage
- Health monitoring (pulse, SpO₂, fatigue) — via CWISS smartwatch, detecting heat stress before collapse
- Up to 30% reduction in safety rule violations — measured across production deployments

**Track record:**

- 10,000+ devices manufactured and in operation
- 30+ completed projects across CIS and Europe
- 8–12 weeks from agreement to working pilot
- Reference deployments at national-scale railway operators

CTRL+N works with railway infrastructure owners, EPC contractors, and safety technology integrators across GCC, Europe, India, and South East Asia.

Headquartered in Belgrade, Serbia (R&D) with operations in Dubai, UAE.
