Two kinds of Steam Turbine. Most models will be "impulse" turbines due to the difficulties of producing the complex curves for a reaction turbine. Most commercial turbines are reaction. With an impulse turbine, steam velocity is everything, but there are tradeoffs. Steam is heated & can expand. In that case, providing more volume just before injection to the rotor blades converts as much heat as possible to velocity. So, a diverging nozzle (such as the "trumpet" nozzle) works better.

Very little is known about the North British Locomotive Company's Reid-MacLeod Turbine Locomotive. This was an early attempt at a steam turbine locomotive, but it was not the North British's first.

The N&W's Jawn Henry: The Norfolk & Western's experimental Jawn Henry was the last in a short series of steam turbine locomotives tested by three different railroads between the 1930s and 1950s including the Pennsylvania and Chesapeake & Ohio.
