**** Route 244, 301 and 472 changes linked
***** Route 54 to run in two sections. Half of the buses run from Woolwich to Beckenham Junction with the other half running from Blackheath, Royal Standard to Elmers End
Certainly nothing I'd want to happen though (other than the 161 changes which should provide the capacity needed between Woolwich and Greenwich following the 180 changes) and 286 changes which should allow double deckers to run with buses missing the QMH loop, providing the extra capacity needed.
If there are any routes I've missed, please let me know.
