Been enjoying your blog...I maintain emergency engine generators here at our regional airport,so any info on power systems interests me!
So while I was in Japan in the US Navy I got to ride the Bullet train there. What a ride! Naturally I was fascinated by the power system & started studying other bullet train systems mainly Europe's. So why do some European railway power supply systems use 16 2/3 HZ frequency??? (not 50HZ) Some even use 25 HZ.
WHY???
