Maximum traction cannot be obtained on a rusty rail!  Rust will act like a
lubricant, even if it is not wet, Railway metal wheels on metal rails make
minimal contact, and rely on clean surfaces to gain  adhesion. Sand is only
an aid, and not a good one at that. Modern Locomotives use wheel creep
instead of sand. The sand is still available, but not able to be selected by
the Driver at slow speeds, whilst Wheel creep is being utilised.
