Two interesting suggestions , we could pedestrianise Dartmouth Road, or certainly the station end. This would be win win. Buses could easily be diverted as they were when major road works recently.
True major bus stop for 197 and 176 would move to junction of Sydenham Rise and 122 would go the same route but down London Rd.

Wow what a great idea. Why has not TFL thought of this. We could have pavement cafe's by Dartmouth Arms.

Hmm, I wonder what the residents would think of that. Their bus service slashed and lots of noise at night...
