Validation, interpretation and use of railway track acceleration data
Validation, interpretation and use of railway track acceleration data
It has for many years been relatively straightforward to attach an accelerometer to a railway track and obtain data of track accelerations as trains pass. However, not all devices are suitable and there are a number of potential pitfalls in processing and interpreting the signal. The Paper discusses these, starting with issues associated with the measurement itself including the frequency of sampling, filtering and noise. Aspects of interpretation and use of train signature data are then considered. Areas of current debate and disagreement are highlighted, and some degree of resolution proposed, with reference to original and published data. This resolution, and new data on the performance of a complex set of switches and crossings, are significant contributions to current knowledge.

Abstract
It has for many years been relatively straightforward to attach an accelerometer to a railway track and obtain data of track accelerations as trains pass. However, not all devices are suitable and there are a number of potential pitfalls in processing and interpreting the signal. The Paper discusses these, starting with issues associated with the measurement itself including the frequency of sampling, filtering and noise. Aspects of interpretation and use of train signature data are then considered. Areas of current debate and disagreement are highlighted, and some degree of resolution proposed, with reference to original and published data. This resolution, and new data on the performance of a complex set of switches and crossings, are significant contributions to current knowledge.
