Answer:
A steel rail also has a thicker cross section. When the rust forms on the face of the rail it acts as a barrier which then slows the rate of corrosion. ... Therefore for a rail section the loss of strength from corrosion is probably negligible as compared with the loss from friction and wear from the train wheels.
