Step 2: Comparing results before and after maintenance
- The below figure shows the cycle depths & locations for a fault of 9 m on the right rail before
maintenance.
Figure 24 - Plotting a Recording
- The bar chart above shows the result of clicking 'Plot' to display the positions of the cycle depths for
a 9 m cyclic top fault beofre maintenance has occurred.
- The graph shows eight cycles & the fault treshold is 5 mm (everything black is below 5mm)
- Another recording can be plotted over the top of the first recording. This can be used to compare a
rail before and after maintenance. In the example shown, the maintenance removed all but two of the
cycles.
