Railways, telegraphy, postal communication, standardised time, radio broadcasting, and large public works were central to the material reorganisation of colonial and postcolonial India. This narrative review examines how historians have interpreted these systems, with particular attention to the relationship between imperial power, technological mediation, everyday use, and nation-building. It brings together scholarship that is often separated among economic history, labour history, media history, science and technology studies, environmental history, and studies of nationalism. Earlier accounts commonly emphasised technological diffusion and the capacity of infrastructure to extend military, administrative, and commercial control. Later work has retained these concerns while demonstrating that technological systems were neither socially neutral nor uniformly effective. Railway workers and passengers, postal runners and traders, journalists, radio listeners, regional commercial associations, nationalist organisers, displaced communities, and technical personnel altered the operation and meanings of infrastructure. The review also examines continuities and discontinuities between colonial projects of improvement and postcolonial development, especially in broadcasting and hydraulic construction. The selected literature indicates that infrastructure did not simply integrate territory or produce national consciousness. It created uneven capacities, differentiated access, new forms of discipline, and opportunities for appropriation and political contestation. The review identifies three priorities for further research: integrated study of interconnected systems rather than isolated technologies; greater use of vernacular, regional, labour, gender, and caste archives; and closer examination of maintenance, breakdown, environmental consequences, and infrastructural exclusion.
