Predge
Predge is a Swedish supplier of predictive maintenance software for railway rolling stock and infrastructure, headquartered in Luleå and delivering decision support through modular software-as-a-service solutions.
Founded in 2013 with roots in academia, the company employs approximately 16 people according to its most recent annual accounts. Its registered parent is Predge Holding AB, with website at predge.se.
Core products
Predge’s railway offering centres on two product lines: Predge Rolling Stock and Predge Rail Infrastructure. Both are subscription-based decision support services for operation and maintenance planning.
The Rolling Stock service includes wheel damage prediction, bearing failure prediction and detection of on-route load shifting. A Bogie Performance feature identifies vehicles with deviating running behaviour.
The company positions its services as planning tools rather than monitoring dashboards. Predictions of remaining useful life and damage risk are intended to let operators align maintenance need with available workshop capacity.
Technology approach
Predge applies a hybrid modelling approach that combines machine learning with physics-of-failure and railway domain knowledge. The company takes a vendor-independent view of data, integrating inputs from existing wayside and onboard sources rather than requiring proprietary sensors.
This data-agnostic model allows customers to build predictive maintenance on infrastructure they already operate. According to the company, deployments are scoped to start small and scale iteratively.
Market position
Predge’s customer base is anchored in Nordic heavy haul and freight. Reference customers include the Swedish freight operator Real Rail Sweden, part of the Sandahls Group, and the mining company LKAB, whose iron ore traffic in northern Sweden runs at axle loads among the highest in Europe.
In 2023, the company entered a cooperation with Vossloh to develop predictive models for switch machines, extending its analytics from vehicles to infrastructure assets. The partnership was announced as a route to making failure forecasts for switches available to a wider market.
The company presents at international rail industry events, including RailTech Europe and the Heavy Haul Rail conference in Australia. Its solutions also serve the mining sector through a conveyor monitoring product line.
Recent activity
In September 2025, the UK-based entity in charge of maintenance Davis Wagon Services adopted Predge’s wheel damage prediction for the biomass wagon fleet operated for the power generator Drax. The deployment followed a pilot and validation phase and uses existing data infrastructure rather than new trackside equipment.
Predge stated it would use the UK leaf fall season to gather further performance data on its wheel damage algorithms. The project marks the company’s expansion from its Nordic base into the British freight market.
