Abstract
Based on the field research during the trip with the train, the author reflects on the dynamics and interaction between spatiality and mobility, seen through the lens of the mutual inter-defining of space and mobility. The trip opened the opportunity to analyze space as an assemblage of geography and mobility. This allowed the author to see the contrast between the artificial spaces of Nukus and traditional mahalas, the difference between the planning logic of the old and new sides of Astana, and the diversity of mobile actors, depending on the type of railway trains. The conclusion is that Central Asia's infrastructure is a very distinctive combination of imperial, Soviet and national infrastructures. Infrastructure and urban design do not fully shape mobility. Mobility forms its own geography, successfully entering the co-production of space with different layers of railway agency.
