Norfolk Southern Corp., the railroad still cleaning up the environmental and financial damages caused when one of its trains derailed in a small Ohio town, has fired its top executive and chief legal officer after concluding they had an affair that violated company policies.

Norfolk Southern said that a preliminary investigation concluded that CEO Alan Shaw and executive vice president and chief legal officer Nabanita Nag violated company policies by engaging in a consensual relationship, according to a press release Wednesday. The company fired them each “for cause.”
