In 1926, a group representing residents along the Cantareira tramway, which connected downtown São Paulo to the northern area and Guarulhos, petitioned the state government with an urgent request to hand over the electrification project of the railway to Light, a local electricity company. The residents believe that this decision is critical, as Light has recently experienced an overabundance of electrical energy following the conclusion of the water crisis that had plagued São Paulo.

The petition explicitly warns against any alternative solutions, asserting that failing to assign the electrification work to Light would be a 'grave error.' The group emphasizes the need for the tramway to have a standard gauge line similar to the existing urban network, which would facilitate better integration of the tramway into the city's transportation system. This reflects the community's desire for improved public transport infrastructure that is both efficient and sustainable.

This call for electrification not only highlights the immediate needs of the residents but also hints at broader implications for urban planning and environmental considerations in São Paulo. As the city emerges from a crisis that impacted its water supply, efforts to modernize public transport with electricity could represent a significant step towards sustainability and improved urban living conditions.
