> Link please... Mission impossible for now, because sleep is long overdue. Anyway, something anecdotical: At the times, when I looked into it about 2008, I discussed that with some people, some of them 'engineers', as in the people who actually drive the trains (both freight and passenger). They also confirmed that, they even learn that during training. Can 15kV at 16 2/3Hz produce such differences? Whatever, as I said before, it isn't limited to rail, grids as they are now aren't as efficient as the models suggest. But I can't re-research this at the moment. I just know I didn't hallucinate that stuff, OK?
