The 6-car stop point and One Person Train Operation (OPTO) stop point on the Brooklyn-bound local track of the 7th Avenue IND Culver station, near Prospect Park under 9th Street and 8th Avenue in Park Slope, Brooklyn. Note the additional notice not to open doors towards the wall, which should be self-explanatory but better safe than sorry. Also note the decayed state of the tilework.
