Video: Prince Charles turns train driver during Bombardier visit The Prince of Wales took a new metropolitan train on a test run while visiting the company's Derbyshire factory to support British manufacturing. With the help of driver Rag Gahonia, who has worked at Bombardier for nearly 35 years, the prince sped down the track at 45mph. Mr Gahonia, 51, said: "I showed him how to drive and he followed all the instructions and was really good. Did it perfectly. Stopped nice and smoothly. The trains are part of a long-running contract to replace existing stock on London's Metropolitan, District, Hammersmith and City and Circle underground lines.
