I hate to say this, but the person who said that the bridge and tracks could be back in service in six months is kinda, well, dreaming. There are no(!!) tracks across the bridge at all. They end at the station on Belmont Ave (sorry, I don't know the name offhand). The tracks don't begin again until about 1/4 mile from Ivy Ridge station.
Also, does anybody know the structural integerity of the bridge? Granted, I've never seen a train roll across that bridge in my lifetime, I was born too late (just a few years, but I still missed it.) SEPTA did a cosmetic restoration, but that was to stop the face of the bridge from falling down (and yes, it was literally falling down, on people's cars too. Sounds familiar with the RDG bridge that runs up Cresson street too. What a trend.)
Speaking of tracks, you need signals to govern these trains. There are none in place past the bridge. Need them too.
I've said this before, a long time ago. Once you get past Ivy Ridge, it's a jungle. Literally. I drove over the once was crossing that now begins the Valley Forge bike path and looked into the woods. I couldn't believe that just twenty or so years ago, a trian used to cross here. I couldn't get over it. Oh and between Shawmont Ave and the beginning of the bike path, the people who live along Nixon Road have "extended" their yards onto the former ROW. About the only thing that's still in place along that former line are the catenary poles with the high voltage lines on the tops of the poles, not the catenary themselves.
Okay, I'm going to end this now before my hands fall off.
