The São Paulo Public Ministry (MP-SP) has initiated a civil inquiry to assess the possibility of extending the operational hours of the city's train and subway services, particularly focusing on Saturday services. The investigation aims to examine the implementation of uninterrupted services during the weekends and has requested technical data from the São Paulo Metro, the CPTM (Companhia Paulista de Trens Metropolitanos), and various private operators. The inquiry, being led by prosecutor Moacir Tonani Júnior from the 6th Promotoria de Justiça de Habitação e Urbanismo, was formally initiated in January following a complaint made by federal deputy Erika Hilton (PSOL).

The focal point of the complaint raises concerns over the reduction in operating hours from Saturday to Sunday following the pandemic, noting that services used to operate until 1 AM on Sundays but are now limited to a midnight cut-off. The representation highlights the negative impact this schedule change has on passengers who rely on public transport during the night, particularly those who may work late or have other urgent travel needs.

This inquiry could have significant implications for public transportation policy in São Paulo, particularly as the city looks to adapt its services to better meet the needs of its residents post-pandemic. Extending operational hours may improve accessibility and convenience for commuters; however, it will also require an evaluation of the potential costs and logistics of implementing such changes.
