T | Wonderland is a long-range line starting off with a journey through Union and Sullivan Squares, then crossing the Mystic River into Everett. Once in Everett, you remain proximate to the Mystic River, past a long-time industrial area rapidly gentrifying into a multifamily community as you proceed straight into the municipal center of Chelsea. Proceeding north out of Chelsea, the longest line in the BYKE Network enters Revere Center before turning east toward Revere Beach, the oldest beach in the United States, and Wonderland, the terminus of the MBTA Blue Line rapid transit.
