After Park Place, the line broadens from one to two tracks and the right-of-way 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 unused southbound track also enters a tunnel, but curves 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 inner two tracks.
