It is the transportational system of Philadelphia and it's surrounding areas. It is pretty shitty and unreliable and is known for having strikes. There was also a train on the regional rail that had crashed while they were on strike. The train only ran while they were on strike because the regional rail is a different company or union than septa but is still called septa. It consists of buses, subways although there are only like 2 subway lines lol, trolleys, and regional rail. They never arrive on time and you should just go drive unless it is to the phillies world series.
