This problem of coverage of sand on the ballast is for only some distance. Not in the whole section.

Obviously because sand blows in the wind, and drifts like snow...

However, this doesn't have any bearing on your question as I skimmed it the first time, but...

Locomotives are equipped with a supply of sand and sanding devices to aid in traction...

If there's wheelslip (which can occur anytime) or weather related slippage, dropping sand from the sanders helps traction. They are pneumatic.
