[quote user="Sawtooth500"]What exactly was the point of elephant ears on a steam loco? Like I've seen some challengers that had them, and some that didn't.[/quote] Hi, they were certainly useful for speeds beyond 70mph and especially while drifting or on plains with harsh winds. Speeds of Greyhound-Challengers pulling "The Portland Rose" may have been faster than 70mph on occasion. Quite a lot ( <A href="http://www.utahrails.net/up/ttg-challengers.php">http://www.utahrails.net/up/ttg-challengers.php</A> ) had them at certain times. They are called by their inventor "Witte" usually, but do not know the American definition. Big Boy 4019 had them also for short time but was used just a short time without any notice they were a success or useful on this type.  The bigger ones ( I think they are the ones usually called "Elephant Ears" ) are "Wagner"-Style, another RR-Engineer. They could substitute a full streamlined body by 80%, another important factor, saving power and fuel.  Cheers lars
