Second only to New York City the Washington DC Metro or Metrorail is the second busiest rapid transit system in the United States. With 6 lines, 91 stations and 117 miles of track and daily trips averaging over 700,000, it is quite a service.
We had several rides on the Metro on our trip with the grandkids and they really enjoyed the experience, it was a bit hectic to figure out all the ins and outs but overall a good way to get around the congested DC metro area.
I snapped this in one of the stations we travelled though, thought this would be a great B&W, and I like these type of architectural shots.
Thanks for looking!
