Railway maintenance activities are often documented manually, which can be time-consuming, error-prone and difficult to standardize across fleets and projects. Maintenance operators frequently face challenges such as incomplete records, delayed reporting, inconsistent location references and limited traceability of performed work. As railway infrastructure becomes increasingly digitalized, operators require automated solutions that improve transparency, data quality and operational efficiency.

Automated maintenance documentation reduces administrative effort while improving the accuracy and consistency of maintenance records. By automatically detecting and georeferencing maintenance activities, operators can generate reliable digital records without manual reporting. Key benefits include improved traceability, faster reporting workflows, better asset management, enhanced compliance support and increased operational efficiency across railway maintenance projects.

Benefits at a glance:

• Reduced manual reporting effort
• Improved data quality and consistency
• Faster reporting and analysis
• Enhanced maintenance traceability
• Better support for digital asset management
• Increased operational transparency

A-ROX mPOM combines high-precision GNSS positioning, inertial navigation and machine activity detection to automatically identify and document maintenance work. Activities such as tamping, grinding, milling or inspection runs can be detected, georeferenced and recorded without requiring manual input from operators. This significantly reduces documentation workload while ensuring that maintenance records remain complete, accurate and readily available for further analysis.

A-ROX mPOM is designed for a wide range of railway maintenance and inspection vehicles. Depending on the project requirements, the system can be integrated into tamping machines, rail grinding machines, milling machines, ballast cleaning equipment, inspection vehicles and other specialized railway maintenance machinery. The flexible architecture supports customized integration into existing vehicle platforms and digital maintenance workflows.

Traditional maintenance documentation often relies on manual data collection and reporting, which can lead to errors, delays and incomplete records. A-ROX mPOM automates the collection of positioning and maintenance activity data, creating accurate and traceable digital records in real time. This improves operational efficiency, reduces administrative burden and provides infrastructure operators with a reliable foundation for data-driven maintenance management and reporting.

Key advantages over manual workflows:

• Automated work detection and documentation
• Precise georeferencing of maintenance activities
• Reduced risk of reporting errors
• Faster availability of maintenance records
• Improved traceability and compliance support
• Seamless integration into digital railway workflows

A-ROX mPOM by ANavS is a high-precision GNSS-INS tightly coupled positioning and documentation system developed specifically for rail maintenance machinery and track-bound vehicles. It provides centimetre-level position, velocity and attitude data even in GNSS-challenged environments.

Rail positioning systems must deliver track-accurate localisation, automated work detection, continuity during GNSS outages, and integrated documentation.
