Port Clinton, Pa.-based Reading & Northern Railroad says 2013 was the most successful year in its 30-year history. The regional railroad—twice named Railway Age’s Regional Railroad of the Year since 2000—grew its carload business by more than 14%. Its overall traffic, which included export coal business, was up almost 9%.

The Reading & Northern Railroad has filed a lawsuit seeking to stop a regional authority in eastern Pennsylvania from proceeding with what R&N is calling a “no-bid” contract for rail service.
