Norfolk Southern has been instrumental in transforming Reading & Northern into an efficient short-line railroad in Pennsylvania because of its remarkable way of keeping close business relationships, said Andrew Muller Jr., Reading & Northern chairman and CEO. "Our interaction with NS Operations has been good for so long that I almost take it for granted," Muller said. "NS helps us to meet our customer's service expectations, and as we raise the bar on our own performance, NS is there to help us exceed expectations."
