Is this from the stones, or because the stones are polluted? There has been a lot of talk about where to put the old stones here in Denmark (another densely populated region), because if you “put” it too close to sources of drinking water all that pollution they’ve soaked up over the years will eventually get into the ground water.
If it’s that dust, and not “just” quarts dust from the stones themselves, then I wonder if switching will help. I mean, the trains are still going to drop whatever it is they drop as they ride along.

- londons_explore 3y agoI wonder why railway ballast is polluted...? Has someone been running trains for years which leak loads of oil or something?
- skeeter2020 3y agoit's not; it's the dust from the actual stones themselves not a contamination.
- devjab 3y agoIn Denmark it’s because we still have diesel trains from the 80-90ies because their replacements didn’t work. (Don’t ask). I’m not sure the electrics they plan on implementing will have the same issue.
