Train service on CPTM’s Line 13-Jade resumed at 6 a.m. on Wednesday, Aug. 5, after a railway workers' strike [1].

The restoration of service is critical for commuters in São Paulo, as the disruption affected key transit corridors and impacted the movement of passengers traveling to and from the airport region.

Trains began operating again on the stretch between Aeroporto Guarulhos and Engenheiro Goulart stations [2]. This follows a total suspension of service on Tuesday, Aug. 4, when railway workers initiated the strike [3].

The strike's impact extended beyond Line 13, with reports indicating that Lines 11, 12, and 13 were all affected by the labor action [1]. The Companhia Paulista de Trens Metropolitanos (CPTM) announced a minimum operation to mitigate the disruption to passengers.

Despite the resumption of some services, tensions remain between the company and the unions. The CPTM president said that the union members are politicking the agenda rather than discussing labor issues [2].

CPTM officials said that the resumption occurred after the strike's impact lessened and the company moved to implement the minimum operation required to maintain basic transit [1]. A spokesperson for CPTM said, "The compositions returned to operate at 6 a.m. on the section between the Aeroporto Guarulhos and Engenheiro Goulart stations" [2].

The labor dispute has created significant delays for thousands of commuters who rely on the metropolitan rail network for daily transport across the city's eastern zones.

The compositions returned to operate at 6 a.m. on the section between the Aeroporto Guarulhos and Engenheiro Goulart stations.

The resumption of Line 13-Jade services represents a partial victory for CPTM in maintaining basic infrastructure during labor unrest, but the broader conflict persists. Because the strike affected three major lines, the incident highlights the vulnerability of São Paulo's transit network to organized labor actions and suggests a deepening ideological rift between railway unions and CPTM management.
