Thank you, Fred, for posting this article!
It brought back memories from childhood, when my grandpa (he was a station master and I spent every free minute on 'his' station) showed me a big book with all these giant American steam engines. I remember the pictures of the AT&SF loco with the harmonica hinge in the boiler, and also the mighty ERIE triplexes. Oh how I wished we had such locomotives here in Switzerland!
Unfortunately my grandma gave the book away when grandpa died.
She didn't care about my protests - and so it was gone for good... And later I never found out the title or the author of the book.
