It's curious to see how the italian rails are ¿painted? in white. Anybody knows the reason for that?

P.S.: Amazing shot.

Thanks David, in the summer months in Italy the rails are painted of white for it avoids the termic expansion since in the last years the temperature it is always higher!!!

Thanks for your answer Riccardo!
