as farmland, then mining for brick clay, tanneries, and landfill. The Fitchburg Railroad main line in 1843 was the first rail link constructed through the swampy area in western Cambridge. It still serves as the MBTA Commuter Rail Fitchburg Line. The Lexington and West Cambridge Railroad was branched off in 1846, with the curving connection still visible today, passing under Alewife Brook Parkway, along the west side of the Alewife Station parking garage, and proceeding northwest along the right-of-way of the present-day Minuteman Bikeway. The Watertown Branch Railroad was opened in 1851, branching from the Fitchburg and curving south behind what is now the Fresh Pond Shopping Center on the east side of Alewife Brook Parkway (then merely swampland). By 1852, several spurs were serving local freight customers, including ice houses on the south side of Spy Pond. In 1870, the Boston and Lowell Railroad bought the former Lexington and West Cambridge Railroad, by then renamed the Lexington and Arlington Railroad, and constructed a connection from the Alewife area through what is now Davis Square to Somerville Junction. Most of this connection is now the Somerville Community Path and Alewife Linear Park, but at its western end it passed through what is now Alewife Center and met up with the Lexington, after curving past the stub ends of Fairmont and Lafayette Streets. This new connection also had a southerly fork known as the Fitchburg Cutoff, passing just north of the present-day Alewife Station, crossing the now-removed Fitchburg-Lexington connection, and joining the Fitchburg mainline. A map from 1903 shows these railroads criss-crossing the reservation, as well as Alewife Brook proceeding farther south to drain Fresh Pond. The swampy area is largely undeveloped, compared to the surrounding neighborhoods. The reservation was originally planned by landscape designer Charles Eliot in conjunction with the Alewife Brook Parkway, although it has been substantially altered since its initial set-aside. It forms part of Boston's Metropolitan Park District, established in 1893. The Alewife Brook was straightened and channelized next to the parkway between 1909 and 1912, with road construction completed by 1916. Landscaping was performed by the famed Olmsted Brothers firm. Especially in the 19th, 20th, and 21st centuries, the surrounding land was developed with residential, commercial, and industrial buildings. Storm water management wetland Beginning in 2011, the City of Cambridge constructed a 3.4-acre storm water management wetland in the reservation, just west of Alewife Station. The
