Transition resistance influence of the upper structure track ballast on the rail-to-earth potential at AC railway sections
Introduction. The purpose of the research is to evaluate transition resistance modifications of the upper structure track in passing from the ballast to the ballastless track. These modifications effect the rail-to-earth potential difference. Moreover, they refer to the reverse traction system, to t...
