Re: rear disk brakes
I see the sparks, down here is Southern California, the Rail Road
must use tons of weed killer as there's nothing within fifty feet of the
tracks, and they're usually running in a ditch. each Summer we fight the
clogged, breaking apart catalytic convert starting fires along out
roads. we throw them in jail as if they knew what they were doing.

Could be:
dragging equipment...this can get out of control before the engineer, 30
cars up front, knows anything is wrong.
engineers throwing butts out the window (as someone suggested)
Kids playing with matches along the tracks
sparks from the brakes or wheels against the rail or wheel flanges
against the rail on curves (bad track)...they may well through sparks,
but they don't catch fire themselves.
There is some pretty poor freight track in the area South and West of
Portland on the short lines.
Occasionly, a poorly maintained diesel locomotive will spit fire out the
stacks, but I don't know that it would through sparks!
You should see what happens when they run a coal fired steam locomotive
along track that hasn't seen steam in 50 years. As the cinders fly onto
ground that hasn't burned in all that time, a bevy of firefighters has
to follow the train! Note that virtually all of the restored steam on
the West Coast is oil fired, as it was since about 1900.

Re: rear disk brakes
I think disc brakes on trains are comparatively recent ; older stuff here
does
use the tread brakes you describe.
