Berg Insight forecasts that the installed base of tracking devices on rail freight wagons will grow from 875,000 units at the end of 2025 to nearly 1.4 million by 2030, highlighting both the progress and the remaining headroom for rail telematics adoption.
Rail freight remains one of the more difficult transport environments to digitise at scale. Wagons are long-lived assets, often operate across borders and networks, and are commonly separated from the locomotives and operators that move them. That makes visibility harder than in road transport, where the vehicle, driver and fleet management system are typically under tighter operational control.
New research from Berg Insight points to continued expansion of IoT-based monitoring in this segment, but also shows that rail freight wagon tracking is still far from universal. According to the firm, the global installed base of tracking devices on rail freight wagons reached 875,000 units at the end of 2025. By the end of 2030, Berg Insight expects the figure to approach 1.4 million units.
Annual shipments are also projected to increase, from an estimated 175,000 units in 2025 to around 350,000 units in 2030. Even with that growth, penetration in the rail freight wagon segment is forecast to rise only from 16.6 percent at the end of 2025 to 24.5 percent by the end of 2030.
That is the most important number in the report. It means that, despite rising device shipments and a growing supplier ecosystem, roughly three quarters of the global rail freight wagon fleet would still remain without dedicated tracking devices by 2030. For IoT suppliers, this is a sizable addressable market. For rail operators and cargo owners, it also underlines how uneven digital visibility remains across rail-based supply chains.
A market shaped by aftermarket telematics
What makes this market different from many other connected transport segments is the split between freight wagons and powered rolling stock. Berg Insight notes that modern locomotives and passenger trains typically include some form of tracking and monitoring technology as standard, with OEMs such as Alstom, Siemens Mobility, CAF, Hitachi Rail and Stadler Rail developing connected solutions for their trains.
Freight wagons are different. Tracking and monitoring solutions for them are primarily supplied by specialist telematics providers offering aftermarket systems. The companies named by Berg Insight include Nexxiot, DOT Telematik und Systemtechnik, SAVVY Telematic Systems, Intermodal Telematics, Level Systems, Giesecke+Devrient, Cargomon Systems and PJM in Europe, along with Amsted Rail, BlackBerry and ORBCOMM in North America.
This distinction matters because aftermarket adoption follows a different commercial and operational path than factory-installed connectivity. Wagon owners and operators must justify retrofitting existing assets rather than simply activating embedded systems delivered with new rolling stock. Integration also extends beyond location data: the business case often depends on combining positioning with sensor information such as mileage, shocks, temperature, load status and component condition.
In practice, this shifts rail telematics from a simple asset-location use case toward operational intelligence. The value is not only in knowing where a wagon is, but in using condition and usage data to support maintenance planning, improve service reliability and share more accurate information across the rail value chain.
Berg Insight’s report also identifies a separate group of suppliers serving locomotives and multiple units with aftermarket hardware and software for remote monitoring. These include EKE-Electronics, HaslerRail, Nomad Digital and Railnova in Europe, as well as Railhead, Wi-Tronix, Quester Tangent and ZTR Control Systems in North America.
Implications for the IoT ecosystem
For OEMs, the data reinforces the contrast between new-build connected rolling stock and the much larger challenge of digitising existing wagon fleets. For telematics vendors and connectivity providers, rail freight offers long-term growth, but the moderate penetration forecast suggests adoption will remain incremental rather than immediate.
System integrators and industrial IoT providers should also note the importance of interoperability across stakeholders. Rail freight movements involve wagon owners, operators, shippers, maintenance providers and infrastructure environments. A tracking device that only reports position may have limited value if the data cannot be incorporated into maintenance workflows, logistics platforms or customer-facing visibility systems.
For enterprises using rail as part of multimodal logistics, the forecast points to improving—but still incomplete—visibility. As more wagons are equipped with tracking and sensor devices, rail can offer better information on asset utilisation and cargo conditions. However, the penetration figures suggest that companies should not assume uniform data availability across routes, fleets or regions.
The broader significance is that rail telematics is entering a more mature phase. Growth is no longer just about proving that wagons can be tracked. The next phase is about turning fragmented sensor and location data into operationally useful information in a market where most assets are still not connected.
