Almost three months to the day after being closed by flooding, and five weeks after work to restore the line was halted by several rail cars crashing into the Station Square T Platform, the entire Library Blue Line has reopened. Crews replaced tracks washed out by flooding, as well as repairing several stops and replacing electrical and communications lines damaged during the flood. New drainage was also installed, as well as flood mitigation controls in key areas to prevent future floods.

Of course, because someone at Port Authority walked under a ladder or broke a mirror or something, the line was closed again about 7 hours after reopening after a tree fell onto the line. The tree was cleared and the line re-reopened about four hours later.
