railway cross sections are of i section to relieve the enormous stresses produced due to the weight of the train, as well as they also reduce the thermal expansions along the planes perpendicular to the cross section which is a major advantage
I section has more moment of inertia than any other sections like square or rectangular section. More moment of inertia implies more resistance to bending and hence stiffer.
