🚂⚖️ Inventor Louis Brennan developed a self-balancing #train that remained upright on one rail using heavy, fast-spinning #gyroscopes. The 1910 #engineering project showed how #physics allowed a vehicle to lean into turns and stay stable even when stopped. Archival footage captures the full-scale prototype during its public debut in #London.
