How does the tgv go fast?

The TGV (Train à Grande Vitesse) achieves high speeds through a combination of aerodynamic design, powerful locomotives, and specialized tracks. Its streamlined shape reduces air resistance, while its high-capacity electric motors provide substantial acceleration. Additionally, TGV trains operate on dedicated high-speed rail lines that feature gentle curves and minimal grade changes, allowing for safe and efficient travel at speeds often exceeding 300 km/h (186 mph). This combination of engineering and infrastructure enables the TGV to maintain exceptional speed and reliability.
