but, but…
that is so yesteryear.
a friend of mine got a new “ear” implanted into the bone.
for adjusting and recharging he got a phone sized thing, that has a cable with a magnet on the end.
he puts the magnet to the point, where the audiophone is. the magnet sticks there.
and the commandos for adjusting and the recharging pass throug the skin to the receiver of the implant.
looks, like step by step we will turn into cyborgs.
just to not forget the theme of the thread:
i would be cautious to super-elevate the outer rail.
that would cause more danger, that a long train is drawn by a loco to topple to the inside of the curve.
