The challenge

Rail operators have estimated, not measured.

For decades, rail operators have relied on conductor counts, ticket scans, and modelled estimates to understand how full a train actually is. Seat-level occupancy, the data needed to plan capacity, allocate seats, and improve the passenger experience, simply hasn’t been available in real time.

Closing that gap takes more than a sensor design. It takes hardware that can be deployed across thousands of seats, survive years of vibration and temperature swings, and integrate cleanly into fleets that were never built around it.

The solution

SeatSense, seat-level occupancy, in real time.

Sensative’s SeatSense delivers continuous, seat-by-seat occupancy data, designed from the start for large-scale rail deployment.

  • Seat-level occupancy data, streamed in real time
  • Designed for continuous operation across long service hours
  • Built for large-scale deployment across entire fleets

Designed for deployment

Built for real environments, not lab conditions.

Reliability over thousands of units is a hardware problem, not a firmware afterthought. SeatSense was designed for the rail floor from day one.

Reliable hardware

Engineered for years of vibration, temperature swings, and continuous duty cycles in service.

Easy fleet integration

A mounting and form factor that drops into existing seating without bespoke rework per train type.

Demanding rail environments

Materials and tolerances chosen for the operating conditions of real revenue service.

From design to production

Industrial design, ready for volume from day one.

Coredeq took the SeatSense casing from industrial design through to injection-molded parts at production scale, with the same workflow that runs across our hardware customers.

  • Industrial design tuned to manufacturing constraints
  • Injection-molded casing engineered for tooling life and yield
  • Production-ready from day one, no redesign between prototype and scale
  • Quality and scalability built into the part, not bolted on later
