Moving the bins to the end of the car park improves the entrance to Forest Hill.
The additional lighting, CCTV, and extra hand rails in the underpass should make it a little more pleasant (though more improvements would be welcome).
The eventual new footbridge will have a lift as well as stairs which will be a significant improvement for people with limited mobility.
If anybody has other ideas for improving Forest Hill and Honor Oak Station please come along to the Forest Hill Society AGM on the 15th October where you can put your suggestions to representatives from TfL.
