The question is how they are going to deal with the section with no third rail yet electrified with 25Hz.I believe they chose (LIRR style) third railing Hell Gate to Harold over converting the section to 60 Hz. Paris' western suburbs had both over and under running third rails in the past but their under running third rail was positioned with dual capable shoes in mind to begin with. IIRC, they were also reversible to keep one side to be worn out more than the other.  Kawasaki will have to design a shoe that deals with two systems that weren't designed to be compatible. A much harder task, I think. |
