In this article we discuss how racism and securitization are an integral part of global human mobility since modern times. In these times of exacerbation of vigilance and control, migrants' subjectivities and their relationship with the societies of origin, transit and destination are constantly reconstructed and deconstructed. We analyze the global fortification -walls, fences, bureaucratization- and the resistance produced by the migrants. Through a theoretical-reflective and interpretative analysis of secondary data sources -recent academic publications, documentaries, news in newspapers and fórums-, we used the case study of "The Beast Train", the freight train that crosses Mexico until the northern border. With the United States, as a biopoliticallaboratory to understand human mobility. Raised to this train, we discuss and rethink the violence of the global border regime and the neoliberal government of migration. In conclusion, we propose certain alternatives to the capitalist regime that expels, excludes and externalizes.
