Il deragliamento avvenuto giovedì all'interno della galleria di base del San Gottardo è verosimilmente stato causato dalla rottura di una ruota di un vagone. Lo ha indicato a Keystone-ATS Christoph Kupper del Servizio d'inchiesta svizzero sulla sicurezza (SISI), l'organo responsabile delle inchieste nell'ambito dei trasporti pubblici.
Kupper ha spiegato che gli esperti del SISI hanno percorso a piedi la galleria di base, a partire dal portale sud. Alcuni chilometri prima del luogo dell'incidente hanno trovato frammenti di una ruota e tracce di deragliamento sui binari.
