Greater Greater Washington pointed out that the DC Metro system celebrated its 35th birthday on Sunday. In honor of this occasion, the website re-published its amazing slide show that illustrates the evolution of the Metrorail system from 1976 to present day. View the slideshow here.

Readers may remember this slide show from when it was published during last year’s massive snow storms, which restricted service to the Metro stations that were in existence in 1982. But that service was far more extensive than what was in place in 1976, when the Metro was just the Red Line and ran from Farragut North to Rhode Island Avenue.

Looking at the map from 1982, it is interesting to see that while the Orange and Blue lines were fairly built out, the Red Line stopped at Van Ness going north and the Green and Yellow lines were not even in existence.

Greater Greater Washington’s Dave Alpert notes that the slide show will eventually be updated with the coming Orange and Yellow line service increases and the Silver Line.
