On the morning of Tuesday (6) a man died after being trapped between the train and the door of the Campo Limpo Station platform of the 5-Lilac Metro line, operated by viamobility. After being pressed, the victim was hit by the train.
Who was the passenger who died after being crushed in the SP subway
According to the viamobility, “even after all the visual and sound alarms, he (the victim of the accident) tried to enter the wagon and was stuck in the space between the doors of the train and the platform.”
The doors have an obstruction motion sensor, but it works only to prevent trains from departing with open doors. There are no sensors in the gap between the platform door and the train door.
“Line 5-Lilac has a nationally used system of doors obstruction sensors to prevent trains from part of the doors open. In the case in question, even after the visual and sound alarms, when trying to enter the wagon, the passenger ended up in space between the train and the platform, where there are no platform doors and the wagon, the train broke”, the train explains the dealership.
Lilac line operations were suspended from 8:06 am to 8:30 am, when the operation returned.
How do platform doors work?
Line 5-Lilac has platform ports on all its stations since 2022 to bring greater security. Line 4-yellow, also operated by viamobility, uses the same safety system, as well as the 15-pate line (monorail).
The doors operate with a system called Platform Screen Door (PSD), which avoids passengers or objects on the side of the road through the installation of fixed walls and automatic doors between the platform and the road. The PSD are synchronized with the opening and closing of the train doors.
According to the viamobility, the lilac line has 1,248 doors that go through 262,000 opening and closing cycles per day.
At the time of hiring the security system, the supplier Bombardier delayed the work and was fined over $ 50 million.
In addition to the lilac and yellow lines, some 1-blue, 2-green and 3-red line stations also have safety doors. In 2019, when they were hired, the government of São Paulo stated that these doors are safety equipment that allow “the reduction in the number of road interference, increasing the regularity of trains circulation and users’ safety”.
According to the contract, the doors contracted to the blue, green and red lines should be 2.10 meters high, sensor of people in the span between trains and doors and minimum transparency of 70% in the areas of the facades.
In February this year, the platform doors began to be installed in the Sé, one of the busiest stations in the capital. Other major stations such as Palmeiras-Barra Funda, Corinthians-Itaquera and Tamanduitai also already have the security system.
In an interview with EstadãoCivil Engineer Specialist in Road Transport Security Antonio Clovis Ferraz, retired professor at the University of São Paulo (USP), said the automatic platform -door model is safe and generally decreases the number of accidents.
“It is quite safe, so much so that in countries they already use, the number of serious accidents has been much less with this door. But no device is totally safe. Automation starts from the assumption that the risk is very small, but it exists,” he says.
The overcrowding of platforms and trains, however, contributes to a reduction in safety. “But this is a problem inherent in any mega metropolis in the world,” he said.
