There are places on the negative rail where there are two patches,
which correspond to the spacing of the two negative shoes on a car -
this would probably be around 30 feet. When examined close up, the
patches show that they are areas where extreme arcing has been taking
place. The patches are probably around 2 feet long. This generally only
seems to occur on the negative rail and only seems to have occurred
since the introduction of the 95 stock. They do not actually have to
line up with the normal stopping point of a car.

Not sure this is a uniquely 95 phenomena. We have a few of these around
with the 73TS too.
