A commuter spotted Penelope the snake on Thursday and alerted a train attendant at a Red Line station. Transit authority officials took the train out of service to search it. Train attendant Sharon Lynch - a snake owner herself - caught it.
Penelope's owner, 30-year-old Melissa Moorhouse of Allston, had traveled around with the snake around her neck and lost it between two stations Jan. 6. She's thrilled to have her pet back and says she'll pay more attention the next time she takes Penelope out in public.
