Why not just use a brush? Too much wear and tear on the rails?
- Anechoic 12y agoToo much wear and tear on the brush, it would last about 100 yards before you had to replace it.
- jacquesm 12y agoBrushes like that were/are in use on some trains and trams, they are pushed down by some actuator and then retract when traction is re-established and the wheels have stopped slipping.

- qq66 12y agoI would think you could have a cowcatcher-type metal wedge hovering ~1mm above the rails to clear most of the mess, and then have a brush for the last 1mm.
- thedrbrian 12y agoThat's going to catch every time the train hits a bump or goes up hill
