The Boston Elevated Railway (BERy) was a streetcar and rapid transit railroad operated on, above, and below, the streets of Boston, Massachusetts and surrounding communities. Founded in 1894, it eventually acquired the West End Street Railway via lease and merger to become the city's primary mass transit provider. Its modern successor is the state-run Massachusetts Bay Transportation Authority (MBTA), which continues to operate in part on infrastructure developed by BERy and its predecessors.
