VIA Rail

But unless you know all the folks sitting around you, I think there's still reason to wear them on the plane.

Like I said, getting some respiratory infection while travelling is fairly common, COVID is not different in that respect.

No argument there. But using HEPA filters on a modern train (like the new VIA ones) would significantly reduce risk for everyone. Especially since trains usually don't suffer from the same level of congestion as planes and airports.
