The existing literature on labour movements notes how trade unions have been weakened in recent years. This observable pattern is not unique to South Africa; arguably, this decline represents a global phenomenon characterised by the disintegration of erstwhile militant labour movements. In the case of South Africa, the post-apartheid neoliberal labour regime has fragmented the militant social-movement unionism (SMU) of the 1980s almost to the point of extinction. Despite this trend, various studies have detailed pockets of revival and resistance by workers spread across a variety of sectors and continents. My article seeks to contribute to this literature by drawing on the case study of Mamelodi Train Sector (MTS). MTS was formed in 2001 as a 'mobilising structure', aligned to the African National Congress (ANC) and its alliance partners. Using the notion of space as a theoretical tool, I attempt to understand MTS and the space it organises - the train. MTS utilises the travel time spent going to and from work to offer legislative education to largely unorganised/non-unionised workers. In addition to legislative education, MTS members (self-styled comrades) discuss community issues and matters pertaining to the ANC's tripartite alliance as an attempt to foster a particular kind of identity politics. The data collected reveals that, among other contributions, MTS offers hope and a sense of solidarity to those workers without workplace representation. The comradely sense of belonging, buttressed by a common identity, potentially mitigates the impact of workplace fragmentation - experienced by the majority of workers in South Africa. Organising on the train points to one missing link in our current efforts to understand workers' agency - the geography of transport in South Africa and its related possibilities as a site of revival. With a specific focus on the MTS as a case study, I suggest that the train, as a by-product of apartheid spatiality, represents a strategic location for worker organisation in South Africa.
