I take the Amtrak pacific surfliner a lot and I've noticed that mac laptops will lightly shock me when they're plugged in. I think I've experienced this with 3 different computers over the past 6 years. Might be a useful data point, since I believe the train is an isolated power circuit independent from the power grid (the electricity is generated by the locomotive).
