Track 5 there is an outlet you can plug into. It's between the bench & the trash can
Use the last car of the WB MFL for Amtrak and SEPTA Regional Rail, and the front car for 31st Street / Drexel University. Reverse for EB.
Use the 5th Car when travelling EB to align with most MFL exits. Find it at the bottom of the MFL steps in line with the side trolley staircases.
You can't catch the BSL here, BUT it is a free interchange at 15th.
