A street railway connected Harvard Square with suburban towns like Arlington, Belmont, and Newton in 1854.
Harvard Square remained an important hub for transportation and to local businesses catering to commuters.
In 1912, the Cambridge Tunnel subway service began in Harvard Square and connected the city to Boston's Park Station. Businesses began to suffer because travelers no longer had to venture outside between transfers.
