I know regional rail is more expensive but we live out in country and kid is very unfamiliar with public transportation. Until he gets his philly bearings straight, would he be wiser to use regional rail to get to 30th street station. Once he starts hanging out with other kids and taking subway around, subway should be ok. Or is regional rail still way to go even after he gets bearings straight. And I think u can get subway tokens at Cecil b Moore. Can u buy from person or do u have to use machine. Where do u buy regional rail tickets at?
