There is only one domestic line on the east coast of USA. I believe it’s time to make room for another. The PAO line services and connects local/regional commuters to work each and every day with its bustling city/suburban lifestyle. Starting in the rural town of Thorndale, coast through the busy suburban streets of Montgomery county, through university, entering into the inner city making 4 stops, two surface an 2 under ground downtown. Upon resurfacing, making one stop at university and then towards the outskirts of the city. Enjoy golf courses, parks, and scenic views of the suburbs as you reach the end of the line and cross into New Jersey for the last stop. I’ve attached the route map and shaded out the routes that aren’t particularly important to make the route smoother and quicker without stopping every 2 miles.
