Beluzzo steam turbine locomotive

Giuseppe Belluzzo designed a steam turbine locomotive with each wheel powered by its own turbine. Built in 1908 by Officine Meccaniche in Milan, the locomotive had two axles and thus four turbines connected in series. The steam first drove the turbine on the front right wheel and the exhaust steam was used to drive the turbine on the right rear wheel. This continued with the rear left and front left wheels before finally ending up in the smoke box.

The turbines turned at a much higher speed than the wheels. Different speeds could be achieved with the help of different gear wheels, while forward and reverse travel was made possible by double guide vanes. Although the prototype was in use until 1921, the drive form with several turbines did not catch on.
