Experimental results on low rail-to-rail conductance values

Measurement results concerning rail-to-rail conductance are presented, based on two measurement campaigns performed in Italy at Rigutino (AR) and Anagni (FR) in spring/summer 2003. Rails in the two sites are isolated from the sleepers and the earth and the weather conditions were hot and dry, so the measured conductance values represent a lower bound. Results cover more than three frequency decades from 10 Hz to 10 kHz.
