ABSTRACT
Transport infrastructures are concentrations of different kinds of socio-technical relations. They weave together the long temporalities of infrastructure planning, construction and maintenance with the daily rhythms of using transport. In Sofia, Bulgaria, the temporalities of metro construction and use offer a glimpse of what it might mean to think about post-socialist infrastructure relationally. Drawing on repeated ride-along interviews with commuters, the chapter discusses everyday metro journeys in Sofia in terms of the social practices of reliability and propinquity. The chapter connects these daily practices to the decades-long history of the infrastructure project that is the metro.
