Steam Turbine Locomotive
The steam turbine locomotive was a variant of the steam locomotive and hailed at the time of its development as not only extremely efficient and powerful (which it was) but also that it could compete with the diesel locomotive in becoming the railroad industry's primary main line locomotive.
However, while powerful the design was only efficient at very high speeds and was a maintenance headache for the few railroads which did test them.
In all just the Union Pacific, Pennsylvania Railroad, Norfolk & Western, New York Central, Great Northern, and Chesapeake & Ohio ultimately tested designs of the steam turbine locomotive, which lasted just a few years on each railroad.
