# If a ballast is badly fouled, the clogging will reduce its ability to drain properly; this, in turn, causes more debris to be sucked up, causing more fouling
# These crushed stones are not smooth, they have sharp edges so that the wooden beams don’t slide over each other
# The ballast distributes the load of the ties across the foundation, allows for ground movement, thermal expansion and weight variance
Therefore, keeping these crushed stones on railway tracks is extremely important. So now you know the reason behind these stones.
