steam turbine electric design termed steam electric locomotive produce altogether new type locomotive hoped adopt mature steam turbine technology maritime stationary applications railroad use early specifications detailed streamlined shape wheel arrangement production horsepower pounds force starting effort force generated locomotive prime order generate motion force initially hoped deliver prototype steam turbine locomotive completed december delivered testing spring total prototype locomotives taken years complete design new steam turbine locomotives featured streamlined bodies appearances somewhat similar contemporary diesel designs locomotives lightweight bodies consisting steel frames covered sheet metal aluminum elevated similar afforded greater visibility significantly longer feet afforded safety operating crews total unit measured feet inches length feet width cab feet inch height february issue claimed steam turbine locomotives attain speeds miles hour times
