Tended Cuts Marker Board Time by 1 Hour in NL
Tended partnered with Safelines BV to deploy geofencing across the Dutch railway network, saving up to one hour per shift by eliminating physical marker boards.

AMSTERDAM – British railway safety technology company Tended has agreed a partnership with Safelines BV, the Netherlands’ largest provider of track safety solutions, to deploy its geofencing system on a larger scale across Dutch rail projects, the companies announced 12 June 2026. The deal, which builds on a 2024 collaboration with Dual Inventive, aims to digitise worksite safety processes that have traditionally relied on manual methods, with Tended claiming the system can save up to one hour per shift per worksite by eliminating the physical placement of marker boards.
What Are the Technical Specifications?
Tended’s geofencing system creates digital boundaries around designated worksite zones, triggering real-time alerts when personnel wearing positioning devices on their PPE or machinery-mounted trackers breach a perimeter. The technology includes Virtual Worksite Marker Boards, which replace the manual process of erecting physical signage with digital markers, cutting set-up time by up to one hour per shift and allowing workers to be redeployed to other critical tasks. Supervisors can monitor machinery movements in real time, and the system supports work completion checks by confirming equipment positions before a line is reopened. Tended has not publicly disclosed the precise positioning accuracy (e.g., sub‑metre or centimetre‑level) of its devices.

Where Does This Technology Stand in the Market?
The Netherlands railway signalling market is projected to grow significantly by 2025, driven by accelerating demand for Industrial IoT and modular automation technologies (Source: IndexBox, 2025). Tended’s wearable geofencing aligns with this digital shift, but it competes against incumbent worksite warning systems that rely on fixed infrastructure rather than personal tracking. ZÖLLNER Signal’s AUTOPROVA, for example, triggers trackside audible and visual alarms but does not offer real‑time individual worker or machinery location tracking (Source: ZÖLLNER Signal product overview, 2023). Schweizer Electronic’s Track Warning System (TWS) uses portable warning devices along the track but lacks the site‑wide digital visibility and marker board replacement capability of Tended’s solution (Source: Schweizer Electronic, 2022). In the UK, Tended’s system is already adopted by several Network Rail routes and major contractors including Siemens, SPL Powerlines and CRSA, suggesting strong domestic validation that the Dutch partnership now seeks to replicate. Financial terms and the total number of devices to be deployed in the Netherlands were not disclosed.
Editor’s Analysis
This partnership signals a deliberate move to replace manual track‑worker lookout procedures with location‑aware digital controls in one of Europe’s densest rail networks, a trend that could accelerate as rail infrastructure managers across the EU face tighter safety mandates. The Netherlands railway signalling market’s forecast expansion, underpinned by IIoT adoption (IndexBox, 2025), creates a favourable environment for Tended’s technology, which offers a data‑rich alternative to legacy trackside warning hardware. If the Dutch rollout mirrors Tended’s UK uptake, it may prompt other European infrastructure managers to re‑evaluate their worksite safety architectures.
FAQ
Q: How does Tended’s geofencing technology improve worksite safety?
A: It creates digital boundaries around hazardous zones and sends alerts via wearable devices if workers or machinery cross them, helping prevent track incursions. The system also replaces the manual placement of physical marker boards, a change Tended says can save up to one hour per shift per worksite.
Q: What is the value or duration of the Tended–Safelines partnership?
A: The companies have not disclosed the financial terms or contract length. The agreement builds on a 2024 collaboration with railway technology provider Dual Inventive.
Q: How widely is Tended’s system used in European rail?
A: The system is already adopted by several Network Rail routes and contractors such as Siemens and SPL Powerlines in the UK. The new partnership aims to scale its use across the Dutch railway network, though specific site numbers have not been publicly confirmed.
