Running on conventional steel wheels and rails, the TGV reached an astonishing speed of 574 km/h, pushing the limits of traditional rail technology far beyond what most thought possible. At first glance, it might seem similar to everyday high-speed trains. But this wasn’t a standard run. Engineers had carefully optimized every detail — from aerodynamics and wheel design to power output and track conditions. The train used specially prepared tracks, increased electrical power, and modified components to handle the extreme forces involved at such speeds. What makes this record even more impressive is that it wasn’t achieved using magnetic levitation or experimental systems. The train remained in contact with the rails the entire time, relying purely on steel wheels — a technology that has existed for over a century. At those speeds, even small i...
