Narrative:

Was instructed to hold short of runway 12R at taxiway B behind a B737 company rj with similar flight number. Was holding short of runway 12R at the next taxiway to our left. Ground instructed B737 to cross runway 12R and told company to cross expedite across runway 12R. B737 crossed to the right and I thought I was instructed to cross also. By the time I realized ground wasn't talking to me, I stopped the aircraft over the hold short line. The aircraft was about 1/2 way over the hold short line and well before the active runway. I called the tower and was told he had to do a report due to tower having to stop a departure.
