As much as I'd rather this money go toward infill lines within the city, interurban lines like this are seriously lacking in the US. Connecting a growing population hub to the city center with rail is a great move. Especially when it'll only cost $2/ride.

With the trolley modernization, SEPTA is looking to connect the 15 to 69th St. That'll expand access to KOP jobs for people living along that line as well.

Edit: it sucks we have to pick and choose which of these projects get funded. In a better world, all SEPTA's expansion and upgrade plans would be paid for.
