| Here is part one of a two-part traffic-density map by David P. Morgan entitled "How much moves where on Penn Central." It was published originally in the October 1973 issue of "Trains" magazine, page 16. Textual Quote: "A traffic-density map shows how many tons a railroad hauls where ~ i.e., explains its reason for being or, frequently in the context of Eastern railroading in 1973, its reason for not being. This Penn Central map, revised on March 27, 1973, is a key exhibit in current Congressional deliberations on how to rationalize excess rail fixed plant." |
