Actually, electrolysis in DC transit systems has always been a problem known as "stray voltage" ... you guys have those problems in the form of corrosion of steel everywhere. Back in the "trolley" days, it was known to corrode gas pipes and water pipes and still does unless your rail returns and grounding are *perfect* ...And as to the hair falling out, long long time ago, the IND was lined with mink.
