For what it’s worth, I lived 50 yards from an at-grade freight track in the city, where from 10pm-7am the trains did not blow their horns, relying on the crossing protective lights and gates only, and that worked for me. Charming train horns during the day (yes they occasionally interrupted me when speaking during video meetings, but it was quaint and no big deal), peace and quiet at night. Great neighborhood, quite desirable, and I would be happy to live there again in the future.

Not sure the safety track record, but if it’s favorable, perhaps this kind of program could be expanded.
