I need some information! It seems that I remember reading that the Broadway limited PRR T-1 was articulated ( even thought the prototype was a straight frame) to allow a bit more flexiblity in use on a tight turn on an HO layout for people like me who didn't plan ahead so well.. Purists were offended, but it probably helped sales. Does anyone own one? Are the two sets of drivers able to swing a bit? Thanks, Dave.
