1522 is superheated. I don't know if or how many mainline steam locomotives are saturated, and I myself wouldnt bet on many, just because of the fact that with superheater units you can get more tractive effort out of a particular engine, and thats always a plus when you want to add several extra cars to your consist.

I would suspect that the transition period from saturated steam to superheated steam was probably 1900 to 1920. It should be noted that there were a number of locomotives that were rebuilt from saturated steam to superheated steam. Whether or not a locomotive would have been modified was dependant on it's age, wheel arrangement and performance requirements of the railroad. Many locomotives had long service lives of forty to sixty years too. awalker2002@comcast.net |
