By 1969, PC had, by merger and new acquisition, the most varied roster of electric MU cars ever assembled. Follow the chronology of this never-to-be-seen-again variety in the transitions from three roads to one and private commuter train operation to state operations! Penn Central MU Cars in Color is one of many books loaded with information about the PC and its immediate predecessors. Hardcover, 128 pages.
