Fouling Point

Y F Sung

Secretary, IRSE(HK)

The location on two converging tracks to which trains may run safely on both lines without coming into contact with each other.




Figure 1 Fouling Point

For example:

Fouling point 3.816m =
Width of train (3.312m) + Dynamic throw (0.200m) + Central throw (0.142m) +
End throw (0.162m)


Some railway operators have their own designed figures due to different type of vehicles and environment.
