Preparation of the press release
On the advice of PROSE, BVB set up a working group on this subject and recommended a shortterm reduction in speed, and launched an investigation to understand the safety relevance of each problem identified. PROSE found no operational risk from the maintenance backlog for BVB during the maintenance of the vehicle fleet. As a result, an immediate shut-down of tram operation in Basel was averted.
The causes of the unusual damage have already been solved since September 2018. After this, no more extraordinary damage has occurred to the tracks.
