For those who have never had the opportunity to go inside WMATA’s headquarters located inside the Jackson Graham Building at 600 5th Street NW, it’s quite a trip. The entire office is basically one big shrine to Metro history, featuring several photographs and artifacts. (Plus: one of those spiral staircases built into the floor which is something right out of a 1970s Bond flick.) When DCist stopped by yesterday to talk with General Manager and CEO Richard Sarles, Metro spokesperson Lisa Farbstein showed off the office’s latest piece of Metro history on display, a nearly eight-foot-tall list of stations, many of which never materialized.

Farbstein said WMATA wasn’t sure when the signage was produced, but there are some interesting stations on it, like “Chillum,” “Federal City College,” “Glebe Road” and “Nicholson Lane.” As we gawked, Erik Weber of Greater Greater Washington astutely pointed out the lack of dashes in the station names — which means this was probably created during the early stages of the system.

Any knowledgable Metro historians out there want to try and put a timestamp on this bad boy?
