Water turbine took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" for "whirling" or a "vortex". The main difference between early water turbines and water wheels is a swirl component of the water which passes energy to a spinning rotor. This additional component of motion allowed the turbine to be smaller than a water wheel of
Gas turbine locomotive use a mechanical transmission to deliver the power output of gas turbines to the wheels. Owing to the difference in their speeds, this is technically challenging and so a mechanical transmission did not appear until ten years after the first electric transmissions. The first gas turbine-mechanical locomotive in the world, Class 040-GA-1 of 1,000 hp was built by Renault in 1952 and had a Pescara free-piston engine as a gas generator. It was followed by two further locomotives, Class 060-GA-1 of 2,400 hp in 1959–61. The Pescara gas generator in 040-GA-1 consisted of a horizontal, single cylinder, two-stroke diesel engine
