Subway Confusion

Ok, so I was trying to figure out how to get to the Phillies parade by train and why was their subway system totally confusing me?!
Mind you, I've been raised on this crazy system with 5000 different subway lines:
Yet I can navigate that perfectly (except for when the MTA wants to throw a monkey wrench into the whole operation by screwing up the lines with their "construction"). And when my sis and I went to Boston University for their Open House weekend, my brain nearly exploded when I saw this simplicity. What?! FOUR lines??

Get out of here with that. Give me a real tangled mess to decipher.
