PD CLC/TS 50238 is a series of standards on railway vehicles that defines the interference limits and evaluation criteria for electromagnetic compatibility between rolling stock and axle counter detectors.
PD CLC/TS 50238‑3 is the third part of the PD CLC/TS 50238 series of documents that give recommended individual limits to be applied to establish compatibility between RST and all selected types of axle counter detectors, including any covered by national standards.
The list of selected types of axle counters and their limits for compatibility are drawn on the basis of established performance criteria.
To ensure adequate operational availability, it is essential that the rolling stock complies with the defined limits; otherwise, the established availability of the valid output function of axle counter detectors may be compromised.
NOTE: For wheel sensors and wheel detectors in other applications than axle counters but utilizing the same rail sensors and detectors, transient and continuous interference can be considered as equivalent to axle counter detectors or axle counter sensors.
PD CLC/TS 50238‑3 on railway rolling stock is useful for:
Axle counter detector is a detector consisting of the axle counter sensor and of the detection circuit, which includes general filters and rectifiers.
PD CLC/TS 50238‑3 demonstrates the compatibility between rolling stock, traction power supplies, and train detection systems for a specific route or specific railway network.
PD CLC/TS 50238‑3 provides an interference mechanism of axle counters comprising the sensor on the rail and the detection circuits in the trackside equipment.
PD CLC/TS 50238‑3 specifies a margin that is required to meet the performance requirements with regard to the reliability of counting.
PD CLC/TS 50238‑3 navigates you through the compatibility requirements and evaluation for RST compatibility with individual axle counters.
Measurement parameters and emission limits for rolling stock are provided in PD CLC/TS 50238‑3 for demonstrating compatibility with existing types of axle counter detectors.
Overall, PD CLC/TS 50238‑3 provides details on occupancy detection of the part of railway networks in order to provide safe and uninterrupted rolling stock movement and improve the required reliability of axle counting systems.
