DATA & FILE OVERVIEW
--------------------

This dataset contains:
Figure_data.xlsx

This contains the data contained in each figure of the paper.
The data for each part-figure is contained in a separate sheet of the spreadsheet.

The figures are as follows:

Figure 2. Sound power per metre for a unit velocity of the rail. 
Figure 3. Sound pressure radiated by a unit velocity on the rail; receivers at 7.5 m distance and different heights – case without ground. 
Figure 4. Sound pressure level for a unit sound power level; receivers at 7.5 m and different heights – case without ground. 
Figure 5. Sound pressure level difference due to including ground reflections, for receivers at 7.5 m distance. 
Figure 7. Effect of introducing the metro train on the sound pressure level, without ground. Receiver distance 7.5 m and height 1.2 m above the rail; results for near rail. 
Figure 8. Effect of introducing the metro train on the sound pressure level, without ground. Receiver distance 7.5 m and height 1.2 m above the rail; results for far rail. 
Figure 9. Angular distribution of predicted sound pressure level at 15 m from the track centre. Sound pressure due to unit vertical velocity of the left rail in one-third octave bands
Figure 11. Change in the sound power level when the train body is introduced with different train profiles. 
Figure 12. Sound pressure level with the train body relative to the result without, for different train profiles – including ground effect. 
Figure 13. Sound pressure level from the rail, at 7.5 m distance, shown relative to the results for a line source – with no ground. 
Figure 14. Sound pressure level from the rail, at 7.5 m distance, shown relative to the results for a line source – with ground effect.
