This dataset supports the publication:
Powrie, W., Le Pen, L., Milne, D., & Thompson, D. (2019). Train loading effects in railway geotechnical engineering: ground response, analysis, measurement and interpretation. Transportation Geotechnics.
The attached excel contains the figure data from this article wherever feasable.
Most data is generated from the equations given in the text.
Data is saved on a tab per figure basis.
Data for redrawn figures cannot be supplied.
The figures are as follows:
