got the full route done. no through-routing possibility at the moment, but it would be very easy to unite the 101/102 and the Girard Avenue line. next up will be squeezing in the NHSL

Lots of great opportunities for through routes if I can plan it out right. Might go back and four-track the line down Market Street to expand the options

9 is the full route, 4 is the old Chestnut Hill West to Center City via the Callowhill Cut route (now cut back to Mon-Sat daytime service, Broad-Ridge Spur sort of hours)

Branches will recreate the modern NJT River Line, plus one that runs up the Marlton Pike through the Cherry Hill and Moorestown Malls, then to Mount Laurel Township.

The future Spectrum site was the trolley station for the Sesquicentennial Expo. I've been exploring the idea of another South Philly subway routing as if built mid-20s, this would be a natural terminus. Would give a bit of Penn Station/MSG flavor to the alternate history Spectrum.

Here's the final alignment I'm going with for this. Imagined as if this were built around 1970-80s, during the brief US transit boom that gave us WMATA, MARTA, etc. The line came in over I-76, around Veterans Stadium, before terminating at an elevated complex next to the Spectrum and JFK Stadium.

Rerouted the final approach to be more friendly to future buildings being added. Would be interesting to pull up old maps and rebuild the line as if it were built around the same time as JFK Stadium with the pre-I-76 constraints (presumably that would just be straight down Oregon to 10th or Broad)

The Airport Line terminal platform at Market East had a spare track, so I terminated it there to maximize transfers for now. Appropriately for Halloween night, this sets up the possibility of an extremely cursed one-seat South Philly to airport route.

not sure if Phillies fans or Mets fans will be more upset about the temporary route branding that I've decided on until I figure out where to send this line

One thing I like about this is that by having a standard stripe on the signage template, you can tweak it for special stations. Here's an example for Temple, while the effect with Penn is a bit subtler due to the color similarity.

Inspired by the Chicago 'L' bicentennial scheme and the upcoming semiquincentennial, I think we have to go red-white-blue on the stripes. Line bullets move all the way to the right.
