Well not surprised this little scheme has been wedeled out of the woodwork again. Two buses go too Honor Oak Park station, the P12 and the P4. Do what everyone else does and either walk to Brenchley Gardens and catch it there or walk to the top of Forest Hill Road into Honor Oak Park and catch either there.
Have you not seen the amount of congestion and pollution which already occurs every morning on Forest Hill Road, and you want to add to it. REALLY!!!!!!!!!!!!!!!!
Not particularly helpful for those who can't walk up the steep hill to the top of Honor Oak Park in the first place.
For some reason TfL provide an excellent bus service to Peckham Rye station with the 63/363, but if you want to reach Honor Oak Park station, it's clunky and Forest Hill station is two buses or a 5 min walk from the bottom of Honor Oak Road on the P4.
