After the fatal accident of a SBB train attendant and experience that had been dragged between Baden and Wettingen AG of a train of type unit car IV, discovered by the Federal Railways in the case of a large control on this Zugstyp 572 error on the doors. 69 doors, they found safety-related defects in the functioning of the anti-pinch protection.
But that’s not enough. New Figures show: the SBB had to hold the anti-trap function on this type of car maintenance. In the past five years, 328 maintenance measures have been triggered, such as an SBB spokesman confirmed. About once a week and had to be replaced at a door a little, adjusted, or repaired. This high number of defects and deficiencies in the anti-pinch is controversial. Because this is intended to ensure that a door opens when someone is between the door and the door frame.
In the case of the trade Union of transport personnel SEV is surprised by this number. “Every year, sixty cases, in which the danger is not that the anti-trap function works, I find terrifying”, says trade Union Secretary Jürg Hurni. This is to show that the SBB for maintenance would need to catch up. To do this, there is a need for more personnel in the maintenance.
“If the SBB regularly receive messages about Defects in the anti-pinch by the staff, quite a pattern,” says Hurni, “namely, that the pinch protection system is the Problem”. With this Knowledge, the SBB had to reduce the interval of the studies.
SBB check maintenance
From the SBB, it means that the maintenance of the trains will be subjected to the fatal accident of an external investigation. Therefore, any questions about the maintenance could only be answered after completion of this Review. The question of whether it is in the 328 and broken to an extraordinary accumulation, remains open. The Supervisory authority of the SBB, the Swiss Federal office for transport, also refers to the Review of the processes.
it is Clear that The SBB each of the doors to test approximately fifty Times per year. Every few days they are to be examined in a simplified, two-months in-depth. It comes to repairs, is due to the frequent use of the doors clear.
But together with the large control found defects of a is clear: In the maintenance, everything runs smoothly. Otherwise, you would not have found the thorough examination within the shortest possible time so many security-related defects.
That the doors of procedure do not always work according to the is apparently already known for a long time. CEO of the SBB, Andreas Meyer said in an Interview shortly after the tragic death of the train attendant and experience, that he knew nothing of defects on the doors. Completely different it sounds to the SBB staff themselves. In the aftermath of the accident train reported that the doors should always make problems.
three years
checks an Insider in the maintenance of the vehicles says that the problems at the doors of the unit car IV had been known for longer. He has been working for some time in the area of vehicle maintenance. “Who has a little idea about technology, sees that the doors are a Problem,” he says.
The type of train has been in use for decades. The result is that the cars are a Patchwork. Different wiring and components have been used over the years. “If you need first an hour, to find out how the wiring is built, complicates the maintenance of the car,” says the Insider.
Already in 2016 the SBB’s car including the doors of the unit IV in a larger control checks. The reason was that the SBB wanted to increase the punctuality. Repeated Türstörungen’t help. Diagnosticians had examined the car at the time, in the ongoing operation and where necessary, re-set, repair or maintenance reported, writes an SBB spokesman.
After the accident, the SBB have launched, in part, to pressure from the Supervisory authority, a number of measures to deal with the door Problem. You have come to the conclusion of the investigation to the conclusion that the unit car IV can continue to be operated safely.
