 The trolley line was extended from Milton to Mattapan on December 21, 1929, with new intermediate stops at Central Avenue and Valley Road.Residents on Capen Street, having to use the Valley Road stop despite the line crossing Capen Street, requested a station of their own; it was considered a likely possibility at the time of the line's opening.After considering the walking distance from Capen Street to Valley Road and Mattapan, the BERy granted the request.
