Wingnut--in response to your query, I find PhilaGeoHistory most helpful. Looking around that block, it appears to have been smaller, denser building stock, in all likelihood typical of modern Chinatown or Old City. Keep in mind that the 1942 WPA map (e.g.) is showing property lines, and for more major properties, what's there--and also remember that the typical property dimensions for residential and industrial do vary quite a bit.
Ch1nish--PATCO is most assuredly not a light rail line. (The River Line is a light rail line.) Rather, it is built to heavy rail frequency and operations standards. PATCO operations also happen to be more frequent (more trains run per line) than SEPTA's, and around-the-clock to boot, so forgive me for being extremely skeptical of your claim that SEPTA has better operations because it is bigger and better "capitolized". (I take it you mean capitalized?) While there are problems within DRPA (like it being a patronage machine), PATCO is certainly one of the, if not the, best-run rail operations in the Philadelphia metropolitan area. I strongly suspect whoever's in charge of PATCO operations there really ought to be in charge of operations over at SEPTA.
Now then, let me plug again my idea for a cheap, easy-to-implement, and expandable alternative to the Ridge Spur as it exists today. The City Branch Cut running along the former Noble St. from Pennsylvania Avenue to Broad Street is reasonably close to the major destinations of that part of Center City, is close to the neighborhood of Spring Garden, and passes through the Community College of Philadelphia. Heading up the Pennsylvania Avenue tunnel, the right-of-way in which is largely disused, the line passes by the large apartment and condo structures facing this street and between the Art Museum and Perelman annex. Breaking back into daylight along the former B&O Philadelphia Branch to Fairmount Jct., it passes by Fairmount (the neighborhood) and Lemon Hill in Fairmount Park, as well as the frequent trolley line the 15 at Girard Avenue. Since this ROW is already mostly acquired, reserved, or disused, the only real major cost necessary to connect it to the Ridge Spur is the cost of tunneling from Ridge along Noble out to Broad, only about 3.5 blocks, preferably with a station offering a connection to the 23. Otherwise, opening some poorly-placed walls, curving around a poorly-placed support column or two, slapping down some tracks and (at first wood) platforms, and utilizing the equipment already in use on the Ridge Spur is all that's really necessary.
Tunnel costs are mucking with my cost guesstimate, but I'd say between $25 and $50 million is all that's really necessary for a "light" heavy rail line from 8th/Market to Girard following this route--most of it spent on that short tunnel. Remember that is a tiny fraction of the costs of, say, the Second Avenue Subway, or SunRail, both of which have price tags in the billions of dollars.
