wooden platforms, which were a safety hazard, as well as incandescent lighting, although all other stations had been upgraded with fluorescent lamps. The station was demolished upon its closure, and the only visible remnant of the station is a sidewalk street lamp which used to illuminate the staircase leading from the station platform. The line then crosses a bridge over Park Place. Park Place was placed at a lower elevation in 1905 in order to eliminate the grade crossing. To allow vehicular traffic to pass under the line, the street descends to as much as below its elevation on either side of the Franklin Avenue Line overpass. Since the sidewalk remains at the same elevation as on either side, stairs are provided between the road's curb and the sidewalk. After Park Place, the line broadens from one to two tracks Between Park Place and Sterling Place, the line descends to an open cut along a ramp that opened in 1896 as part of the Fulton Street Elevated connection project and enters the near-original 1878 right-of-way, including the original railroad-style tunnel under Eastern Parkway. The south end of the tunnel contains the rehabilitated Botanic Garden station, originally built in 1928. All three stations between Franklin Avenue and Botanic Garden were rebuilt or renovated with elements such as distinctive artwork, masonry and ironwork funded by New York City Transit's "Arts in Transit" program. From Botanic Garden, the line continues on its original 1878 roadbed and connects with the main part of the Brighton Line at Prospect Park. Before entering Prospect Park, trains switch to the northbound track, which continues straight and enters a tunnel. The shuttle terminates on the northbound outer track of the four-track Prospect Park station. The rarely used southbound track (where the Malbone Street Wreck took place) also enters a tunnel, curving sharply west and then south to swing around the Brighton Beach Line tracks, which approach Prospect Park from the northwest and feed into the station's two inner tracks. The southbound Franklin Avenue Line track then connects to the southbound outer track at Prospect Park. Service and railroad chaining Chaining and railroad directions In accordance with the subway's railroad chaining conventions, which measure distances along railroad lines based on the engineer's chain of , the Franklin Avenue Line is chained BMT O (letter "O"). "Chaining zero", the geographical point from which the distance to locations along the line
