The PRR T-1 Steam Train may have broken Mallard's record after all!
https://prrt1steamlocomotivetrust.org/ - Please help fund the T-1 Trust! They are a wonderful organization, building an advanced new 4-4-4-4 T-1 steam locomotive from scratch!
Another video about an American steam train supposedly breaking the speed record held by Mallard! This time, I have a good information book on hand:
American Steam Locomotives, Design and Development, 1880-1960. By William A Withuhn
