I may be making a day visit to Philadelphia in a few months and given the amount of time I have I want to know which lines are worth visiting the most. I know there's the subway-surface trolleys, the 101 and 102 trolleys, the route 15 trolley, the Norristown High Speed Line, the NJT River Line, and PATCO, plus the SEPTA commuter rail lines. Obviously I'd like to ride all of them but I don't have the time. Remember I only have a few hours to do this so I can't go on everything. Thanks!
