Well that's interesting. Rather than using high-pressure water jets, they're gonna try freezing the sticky clag that forms on the railhead.

Under the new method, pellets of dry ice are fired in a stream of air, making leaves frozen and brittle.
The dry ice then quickly turns back into gas, causing it to expand and destroy the leaves.

Actually I can see a flaw in their cunning plan...there's currently a serious shortage of CO2 - and they'll need tons of the stuff for this.
Oh dear!
