Book chapter published in Jóvenes, significaciones y escenarios de riesgo: experiencias y narrativas diversas (UATx). Explores the subcultural dynamics of writers who clandestinely enter railway yards in Mexico to stamp their works on cargo train cars.

The text details the railway infrastructure as a physical channel for transnational communication hidden from the everyday view of the city. It analyzes affinity networks and stealth tactics developed by local writers to connect with the North American graffiti scene, challenging traditional geopolitical ideas of borders and public space.
