I know. Just being my usual self. ^_^

Probably from dragging stuff or wheel/brake sparks.
Under normal use the wheels get very hot. Never seen
an axle sieze but if it did that would drag steel on steel
and make one hell of a lot of sparks.

that's the #1 cause around here.

Most of this area is flatlandia so the trains don't brake so drasticly.
I'd suspect areas with steeper grades that wheels/brakes sparking could
be a real problem.
