Overview
- Judicial experts and technicians from Hasler Rail, Iryo, Renfe and Hitachi carried out an on‑site decryption and technical reading of the main juried recorders at the Tribunal de Instancia de Montoro on Thursday, November 12.
- Police‑supervised physical extraction of the raw recorder files took place on March 5 at CIAF in Madrid but those files remained unreadable without manufacturer software and licences.
- The decryption had been delayed for months because the files require Hasler Rail’s proprietary Multirec‑SG/Hasler‑SG tools, a barrier the Junta de Andalucía resolved by funding licence access and Hasler’s attendance.
- The judge restricted Hasler’s role to a descriptive report of the access and loading procedures and tasked other technicians to deliver analytical reports that interpret each train’s behaviour and possible causes.
- Investigators say the two principal JRUs used in the court session were recovered and intact while two secondary DEUTA modules from the Alvia remain missing and AITAT has separately ordered a rail‑wear measuring tool to support material examinations.
