In July 1891, owing to dense streetcar traffic, a result of increasing populations and the industrial strides of the late nineteenth century, a Rapid Transit Commission was created to resolve the transportation dilemma of Boston and its neighboring communities.
The commission researched traffic conditions in the city’s densest areas, namely Tremont Street, and presented a report recommending construction of an elevated railway system and a tunnel for streetcars to alleviate congested conditions in Boston and surrounding areas. Citing this report, the Massachusetts Legislature approved the Boston Elevated Railway Company (BERy) for incorporation on July 2, 1892.
The Cambridge Historical Commission holds approximately 1,200 glass negatives taken by the Boston Elevated Railway between 1907 and 1912. These images primarily document the construction of the Cambridge Subway in 1909-1912.
The Commission also holds a collection of about 200 cyanotypes donated by Frank Cheney. These prints were made from negatives that are not held in the CHC collections. Many of the cyanotypes in the collection depict the construction of the Charles River dam and viaduct.
Others document the construction of the underground tunnel on Brattle Street.
General William A. Bancroft was president of the Boston Elevated Railway from 1899 to 1916 and proved a great influence in expanding the lines in Cambridge. In the words of one writer at the Cambridge Chronicle, “No suburban city is more vitally interested in rapid transit than Cambridge.”
The Commission holds several boxes of BERy cyanotypes in the archives as well as vertical research files in our main office.
