We were told to taxi to Runway 35; via Alpha; hold short of Papa. At Papa; we contacted Tower and told them we were ready. Tower said to hold short of Runway 35. The Runway 35 hold short line on Papa is almost right at Alpha; while the 35 hold short at Alpha is at the runway. I could see the Alpha hold short line when given the instructions to hold short of 35; so I released the brakes and started forward; looking for what I expected to be a hold short line closer to the runway. Just past the actual hold short line; we realized our error; stopped and told Tower. They instructed us to hold our position. We were subsequently cleared for takeoff.The fault is mostly mine. I mentally dismissed the actual hold short line; expecting it to be closer to the runway; as it is on Alpha. The only other thing that could have stopped this would have been for the Tower; who knows intimately the layout of the airport; to use somewhat different terminology such as 'continue to hold short of Papa' or something to that effect.
As pilot not flying I acknowledged Tower and updated the FMS; the nose of the aircraft crossed the hold line between Papa and Runway 35.
A B737-700 flight crew inadvertently taxied past the Runway 35 hold short line. Confusion over the location of the hold short line on Taxiway Papa vice Alpha contributed to their error.
