The São Paulo Metro M stock represents a series of trains manufactured by Bombardier from 2011 to 2014, designed specifically for service on Line 15-Silver, which commenced operations in 2014. This train series marked the introduction of the first monorail system in São Paulo state.
Accidents and incidents
- On 14 October 2016, a train left Oratório station while its doors remained open, a malfunction traced back to a software programming fault in the train’s computer system by Bombardier.
- A collision occurred on 29 January 2019 between two test trains at the then unopened Jardim Planalto station. An investigation by the Metropolitan Company identified human error as the cause.
- In January 2020, loose screws from a track switch were discovered, necessitating speed restrictions along the line for a period of five days.
- On 27 February 2020, an explosion of a tire on the M20 train resulted in a full line shutdown. Repairs conducted by Bombardier and Metro personnel allowed partial service restoration by 2 June, with complete normal operation resuming on 18 June. Metropolitan Transport Secretary Alexandre Baldy suggested that imperfections in the concrete track caused excessive vibrations that damaged the tire’s runflat system, contributing to the failure.
- At approximately 4:30 a.m. on 8 March 2023, trains M14 and M15 collided between Sapopemba and Jardim Planalto stations during pre-service testing. No passengers were present; one operator sustained minor injuries. The following day, while removing the trains, they collided again without causing harm. Both units were subsequently transferred to the maintenance yard without further incident.
