Built for speed and to conquer the Allegheny and Blue Ridge Mountains, at the time of her arrival – and still to this day - she was the most technologically advanced and the last commercially built mainline passenger steam locomotive in the United States. This is the story and celebration of the 75-year legacy of Chesapeake & Ohio Railroad’s No. 614‘Greenbrier’ Class J-3a, 4-8-4 steam locomotive. Her story has many suppositions: celebration, relegation, survival, patience, and multiple reincarnations. She would outlive and surpass all her original expectations and was given a new lease on life by her patron and caretaker some thirty years after her initial completion. Throughout the last seven-plus decades she has been seen by thousands and inspired millions. She is,without doubt, the ‘last and greatest’ of her kind.
