2019年9月19日 · Shortly before I moved away from Pittsburgh in 1983, I was present when the locomotive was towed away from its display site on the first leg of its journey to western New York. Thus, I actually saw PRR 4483 move, rods (some of them) connected, wheels rotating; I don't think there are many people still around who can say that!!!!
