The Infrastructure on those routes has deteriorated to the point that it would be necessary completely rebuild from scratch. Even if Septa acquired extra rolling stock, Its not as simple as ripping up asphalt and restringing wires. While there are many remnants visible, the electrical systems, substations and track are way too far gone. (Septa and PTC have done so on purpose) Rebuilding from scratch means funding, environmental studies and grants as well as the not in my back yard opposition and some times community opposition as well (remember the 59th street standoff)? Id love to go on a tour of the many loops like Wayne and Carpenter, Rising sun and Knor , 60th and Allegheney, and Ogontz & Cheltenham Ave. It would make me depressed to see what Philadelphia once had. The only area that i could ever see being reinstated is the upper end of the route 23 Because the Germantown depot could be used as a car barn to store the vehicles and for the most part the pieces are still in tact. Its time to look at other cities like Portland or Seattle or Detroit and follow their model. Philadelphia needs to get a different company other than SEPTA to build and run a loop around center city, or old city independence hall area. Maybe SEPTA can extend their lines like the 101 from Media to Granite run mall or the Route 10 up 63rd Street to a new City av loop in or around Overbrook Station or the Route 15 to Frankford Arsenal.
