A Swiss train glides over a special track as its wheels shift live from meter-gauge to standard 1.435m — without stopping.
This advanced railway engineering uses variable-gauge wheelsets and automated gauge-changing stations that unlock the wheels, realign them using guide rails, and lock them again with millimeter precision.

Used across Europe and Asia, this system eliminates delays, improves logistics, and connects regions using different rail standards.
A masterpiece of mechanical engineering, automation, and efficiency. 🚆✨
