By means of observation carried out at various railway stations, we documented how passers-by would engage eventful but ordinary situations, mundane ones, with a very low level of involvement. It is this low level of railway stations, both in terms of equipment and as an object of involvement, which makes them a suitable place for experiments on the issue of the minimum moral requirements for our survival with others and with things. It is thanks to a sort of “collective morality”–?widely shared among those using a station, its space, and facilities–?that we can observe only when stations are open to business, that this common space–?an environment with clashes and confrontations–?remains livable.
