Two connecting routes opened in August 1900. New tracks on Harvard Street from Brookline Village to allowed through service from Allston to the subway via Huntington Avenue. The Ipswich Street line provided an additional route between Brookline Village and the subway; service on that line initially ran to Cypress Street. Service using the Ipswich Street line was extended west on Boylston Street from Cypress Street to Chestnut Hill Avenue on September 29, 1900, and to the Newton line at Chestnut Hill on November 19. Through service on the Longwood Avenue branch ended on August 8, 1901; it became a Brookline Avenue–Huntington Avenue shuttle. On May 5, 1903, the Boston and Worcester Street Railway (B&W) began operations. It initially terminated at Chestnut Hill, but was extended over BERy tracks on Boylston Street and Huntington Avenue to Park Square on July 6.
