Since the 1940s, the people of the neighbourhoods (kampungs) around Surabaya’s derelict Ngagel industrial estate have made a living by repurposing the remains of what was once one of Asia’s most modern road, rail and industry networks. The remains—in the form of leftover fuel, labour and factory parts—are used to rebuild and repair improvised transport vehicles like bicycle-taxis (becak), minibuses (bemo) and motorbike-taxis (ojek). The repurposing happens at the limits of a capital-intensive heavy infrastructure of factories, trams and buses. The limits are those points where such infrastructure fails and a household-funded mosquito-fleet of light vehicles succeeds. Repurposing gives those who do it a right to infrastructure by providing the city with much-needed public transport. In Surabaya, public transport begins at its limits through the improvisations of people who live in the productive remains of capital-intensive heavy infrastructure. These people live in Surabaya’s deindustrialized urban core, where life is made in the ruins of infrastructure through the breaking-down of it, the reworking of it, the right to it, and the leakage of it—the means through which rank-and-file people rather than states and corporations forge infrastructure.
