Problem
Current methods for surveying and managing railway infrastructure data are inefficient, particularly in indoor environments and during the design phase, where accurate data management and manipulation are crucial for ensuring railway safety and meeting the increased requirements of advanced systems like ERTMS.
Innovation Solution
A computer-implemented method and database system that processes survey data to create a database of railway network devices, including signaling and infrastructure devices, with linked records for each device containing position, elevation, and connection information, enabling efficient data management and map generation for railway lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional survey methods are used for railway infrastructure data collection, then data can be obtained, but data accuracy and reliability are insufficient for advanced systems like ERTMS
Solution Approach 1:
The survey data is segmented into multiple categories (signaling devices, infrastructure devices, geographical features) with dedicated data structures for each type. This segmentation allows for specialized validation rules and precision requirements for different device types, improving overall data accuracy and reliability for ERTMS systems.
Solution Approach 2:
A comprehensive database system acts as an intermediary between traditional survey methods and ERTMS requirements. The database includes validation rules, data transformation protocols, and quality assurance mechanisms that bridge the gap between conventional data collection and the high precision demands of modern railway safety systems.
2Productivity
If manual data processing methods are used in the survey and design phases, then data can be managed, but human error increases and efficiency decreases
Solution Approach 1:
The database system performs self-validation through automated rules that check data consistency, completeness, and accuracy during entry and processing. The system automatically identifies and flags potential errors, reducing reliance on manual verification and minimizing human error while improving processing efficiency.
Solution Approach 2:
The system implements feedback mechanisms where processed data is automatically validated against predefined criteria, and error messages are provided to guide correction. This closed-loop feedback system ensures high reliability by continuously monitoring data quality throughout the processing workflow.
3Loss of information
If detailed device information is stored for each railway component, then data completeness improves, but data management complexity increases
Solution Approach 1:
Device information is segmented into standardized data fields and categories (signaling devices, infrastructure devices, geographical features) with specific attributes for each type. This structured segmentation maintains data completeness while simplifying management through consistent organization and retrieval protocols.
Solution Approach 2:
The database employs a universal data structure that can accommodate multiple device types through a common framework. Each device type utilizes the same basic structure with type-specific extensions, allowing comprehensive data storage while maintaining uniform management procedures across all railway components.

AI summary
This disclosure relates to a computer implemented method to produce an output file representing a map of a railway line which connects a signaling device or infrastructure device of departure to a signaling device or infrastructure device of arrival of the railway line. This method makes use of a database of a railway network comprising a respective record of a database for each registered signaling device and/or structure device on the railway network. According to one aspect, such a database may be realised by processing at least one CAD, or Excel or text file, containing at least position and elevation information of the signaling devices and infrastructure devices of the railway network, to identify at least one signaling device or at least one infrastructure device described therein and the respective position and elevation information, then filling in at least one respective record of a database for each registered signaling device or infrastructure device, the record containing at least a name field containing a name of the registered device, a position field containing respective GPS position information, and an elevation field containing respective elevation information. The methods of this disclosure may be implemented via software executed by computer.
