(DC)- Metro has released new details about options for creating a second tunnel between DC and Virginia to relieve logjams on the Blue, Silver, and Orange lines. Metro officials say they hope to use the need for a second tunnel as an opportunity to create new stations in areas that currently don’t have Metrorail. Metro says it could save a lot of money by not making any changes to the rail system, but that would create overcrowding and delays, especially after 2040.
