Author/s: Mario Aragón Moya, David Xaubet Martos, Xavier García Torras, Roger Cascante Cirici

The present article gathers the substantial of the project of Inverse Engineering on the first prototypes of the triangular system Talgo (Tren Articulado Ligero Goicoechea-Oriol): the triangular structure known as Talgo 0 (May 1940) and of the prototype of the train Talgo I (1942).
The Inverse Engineering, done using the scantly existing information, has been carried out to be able to recover information about the forbears of the current train Talgo. This study has lasted for four months and has included different areas: not only a study of design, but also we've done a study of the supposed behavior of the prototypes in route and of the materials' resistance.
The project is useful from a historical point of view to reconstruct with divulgative ends those prototypes. In addition, it tries to help to understand the philosophy with those trains were designed and constructed which innovative characteristics have lasted until the most modern high speed Talgo trains.

Keywords: Talgo, reverse engineering, triangular structures, 3D modeling, reengineering, wheel addressed, finite elements.
