Radnor Trail

In college, for my first ever geography course, I did a project on the Radnor Trail. It's a lovely re-purposed trolley line that now serves as a multipurpose trail for the community. The line, formerly part of the Philadelphia and Western Railway, was abandoned for over half a century before the trail was opened to the public (The portion of the P&W that still operates is known as the SEPTA R100, by the way). Google tells me that now there's some serious interest in taking the Radnor Trail past Radnor into Haverford and Tredyfferin Townships. I wholeheartedly would love to see that come to fruition, especially if it means the trail approaches near my alma mater (which is pretty much inevitable).
Unfortunately I seem to have lost most of the photographs I took for my project, save for one which stood out for its subject's bizarre appearance:

The Radnor Razor

My professor suggested it was a razor monument. Others claimed it might be a giant capital T. I think it's either the monolith from 2001: A Space Odyssey, or the remaining pillar of a P&W station overpass. Realistically, it's probably the latter. I know it isn't some sort of crumbling long-abandoned alien technology, but due to its towering height it is a little bit unnerving. I promise you though, the rest of the trail is beautiful. Not just aesthetically, I mean it's a great trail as far as trails go - no grade crossings, nice and wide, paved well, and in a safe area. Best of all, just like most other roads in the Philly area, it ends at a Wawa.
