This dataset contains: DAS strain and conventional lineside monitoring (strain gauges and DIC deflection) data used in the article
Raw strain, down sampled to 200 Hz is stored as a .csv

Processed data used for figures is stored by tab in the .xlxs.

The figures are as follows:

Figure 7 Integrated strain amplitude along the fibre in time, showing sections for later analysis
Figure 8 a) Strain in time at section A-A, b) Strain along the rail at an instance in time, (section B-B), c) Strain beneath a moving wheel (Section C-C).
Figure 9 Foil strain gauge data, (a) unfiltered and (b) bandpass filtered between 0.1 and 3 Hz in section A-A.
Figure 10 DIC data for rail deflection within section A-A.
Figure 11 a) curvature, b) displacements and c) load per sleeper end obtained by analysing strain from the upper and lower fibres at section A-A.
Figure 12 Load deflection behaviour at A-A 5.6 m along the rail (a-c) and at D-D 9.6 m along the rail (d-f).
