Pershing Point would be a very difficult location for an infill station, though. The DC-Metro New York Ave. station the article refers to was a new station built where the tracks were already elevated, adjacent to a wide rail yard. Even without digging, and with lots of open space next to it, it was still
very expensive.
I'd love to see a station in that area of Peachtree, but with the section being underground, I don't see how it could affordably be built. They would need to build a new temporary parallel underground tunnel while it's under construction, one that would be abandoned once the station opened. Or, if they built the station across the interstate north of Dewberry, besides being less desirable because of the distance away, would require an incredibly expensive bridge to hold it.
The best chance, I feel, for a station in that area would be for it to be on a new short northwest branch that would come out of the existing provisions just north of Arts Center. At one point, stations at Brookwood and Northside Drive/I-75 were planned off of the truncated (post-Cobb-vote) northwest line, and this would have crossed the Connector somewhere around Loring Heights. But, even this would require expensive new tunneling and bridging (not to mention a whole new line), and these stations would be only conveniently accessible from the south.
