@forth@neuromatch.social probably just the same CO2 level math that you can use in any other public indoor space? That’s the reasoning I use, personally. Different trains can have different levels of ventilation, occupancy, etc., so you can’t make a prediction without measuring the CO2 yourself (I think). The next level is calculating that against wastewater levels, if you have access to that. The WHO has the bible on indoor airborne risk calculation, with the Big Math: https://iris.who.int/server/api/core/bitstreams/385a5216-f9e5-4a5d-9496-33d3aba07e9f/content
