Narrative:

Our flight was cleared to taxi to runway 31 at mdt. Our taxi route from the ramp was taxiway east to taxiway a to runway 31. After turning onto taxiway a, the first officer and I were completing the before takeoff checklist when the tower instructed us to hold short of runway 31. Looking out the window, it was apparent that there was no hold short line in front of us. I informed the tower that we may have passed the hold short line. The hold short line for runway 31 is in a nonstandard location approximately 300 ft east of the taxiway F and taxiway a intersection. Prior to takeoff, the tower asked me to call them upon our arrival. When I called the mdt tower, the controller who answered the phone stated that they have had problems with runway incursions at that intersection since they've moved the hold short line. (The controller said approximately 17 incursions.) the controller also stated that he would have to file a pilot deviation report. Callback conversation with reporter revealed the following information: pilot stated that because it was a nighttime operation and the crew was completing a checklist, he did not recall seeing any taxiway markings. He has spoken with his air carrier principal operating inspector who did not think there would be enforcement action taken as a result of this event.
