As you probably know, I'm covering the Penn Relays for most of the weekend. I'll be at PPL Park tomorrow afternoon, but I won't be getting there until after the USA vs. the World 4x100 races. So I'll miss the first few minutes of the game, but not too much.
Here's the SEPTA schedule for tomorrow. It's worth noting that because of the Relays and the PIFA festival on Broad Street, there will be a lot of traffic on the Airport, Wilmington/Newark and Media/Elwyn lines. I was told by SEPTA that trains on those lines will have one or two additional cars to handle the extra passenger load.
I'm sure the Schuylkill Expressway will be jammed through Center City as well, because of the Relays. So tomorrow might be a good day to give the train a try.
