Mainrique Extension

With the abandonment of the stretch by CPTM, the electric network was looted. View of the railroad near the São João Novo station.

Since the establishment of suburban trains in the late 1920s, their services have connected São Paulo to the city of Mairinque. With the creation of Fepasa in 1971, the suburban section was transferred to the Regional Suburbs Unit. This regional unit was expanded in the 1970s and transformed into a Metropolitan Regional Division (DRM).

In the 1980s, the service underwent some renovations, with the introduction of the Toshiba trains renovated in Rio Claro and the construction or renovation of the existing stops between Mairinque and Amador Bueno, equipped only with shelters and "humps" for easy boarding of passengers.[3] The service was officially known as "Trem de Mairinque" and nicknamed "Mairinquinho". In 1987, the city of São Roque even considered an agreement with Fepasa for the integration of trains with the bus network of the then public company SanTC (São-Roquense de Transportes Colectivos), but the proposal did not move forward.[4]

On Lines 1, 2 and 3, the track gauge is a non standard 1600 mm, the third rail is 750 V DC and under running. For Lines 4 and 5, the track gauge is 1435 mm and they use overhead pantograph, precluding any connection to the rest of the system, plus the 4 and 5 lines can't connect because the trains on the 4 line use drive-less technology while trains on 5 line are OPTO. Lines 7, 8, 9, 10, 11 and 12 (operated by CPTM) are all 1600mm and use overhead pantograph.
