## Article

Talgo and Renfe have reached an agreement that puts an end to years of tensions over the **S106** project. The solution: **15 Avril trains** will be configured with **variable gauge**, a modification that allows them to run on both high-speed and conventional tracks. [According to Hosteltur](https://www.hosteltur.com/177300_talgo-acuerda-con-renfe-configurar-15-trenes-avril-s106-con-ancho-variable.html?utm_source=rss&utm_medium=rss&utm_campaign=talgo-acuerda-con-renfe-configurar-15-trenes-avril-s106-con-ancho-variable), the deal was sealed in Rivabellosa and unlocks one of the most contentious projects in the rail sector.

**What does this mean for travelers?** More flexibility. A train that can connect cities without transfers, using the same infrastructure. Operationally, Renfe gains a more efficient corridor and Talgo proves that its variable-gauge technology is a real asset, not a promise. **The travel market benefits**: more connections, less downtime, and an offer that competes head-on with air travel over medium distances.

**My take:** This agreement was overdue. We've been hearing "S106 problems" for years like a mantra, and in the end the solution was technical, not political. **Kudos to Talgo** for standing by its product. **Kudos to Renfe** for needing versatile rolling stock to optimize routes. **Hopefully they hit the tracks soon.**
