Figure 10
The image contains two line graphs side by side. The left graph shows the left track longitudinal irregularity with amplitude in millimeters on the y-axis and location in kilometers on the x-axis. The right graph shows carbody vertical acceleration with amplitude in g on the y-axis and location in kilometers on the x-axis. Both graphs cover the same location range from 280 to 280.5 kilometers. The left graph has a blue line indicating variations in track irregularity, while the right graph has an orange line indicating variations in carbody vertical acceleration. The graphs illustrate the relationship between track irregularities and the resulting vertical acceleration of the carbody. All values are approximated.Absolute correlation coefficient = 0.2.
