Enough of all this talk about the new DC Metro map; here’s another old one for you – and this one’s a bit of an oddity. An inspection of the southern leg of the Green Line shows that the terminus was then planned to be at Rosecroft, not Branch Avenue. The preceding station shown, St. Barnabas Road, was also never constructed
The photos of the map were sent to me by Mark Greenwald, who says that these maps were on trains for less than a year – presumably because of the numerous legal issues surrounding the eventual routing of the Green Line, which you can read more about on Wikipedia.
Another oddity – Union Station is still labelled as “Union Station – Visitor Center” long after the ill-fated National Visitor Center closed its doors in 1978.
