SEPTA experts, please chime in here. I've wondered this for years, and got in a heated debate about it while down there a few weeks ago. So, when the subway reaches its southern terminus at NRG, and now both of the tracks are signed as Northbound tracks (even when a southbound train just arrived on said track), how does the train turn around? There isn't a loop or anything, is there? Or is there a fork in the track and coordinated signals right before the train enters NRG station?

A crane picks the train up and turns it around
