Something similar already exists and is in use for example in Zürich Switzerland. Some light rails (specifically the Forchbahn built by Stadler rail) have compressed air jets which clean/dry the track on wet days to help when the track is slippery. You can hear them going off when the train leaves on wet days especially on a hill and the wheels are spinning on the track.
The jets may also mix in some chemical solution to help with adhesion but I don't know.
- iggldiggl 5y agoAre you certain that those really are compressed air jets? The thing I'm familar with are sanders – those are commonly operated via compressed air, too, but their goal isn't blasting contaminants off the track, but rather just getting sand onto the rails in order to improve adhesion.
- sschueller 5y agoI am not 100% certain. It could definitely be sand being sprayed. The old trains don't have it, only the newer ones. I just hear compressed air being sprayed under the train when it's wet and the train is skipping on the track. Something is being sprayed onto the track.
