I should have spotted this one before, but in London the SL3 runs to Thamesmead, which is east of Woolwich. It meets the 96 at Bexleyheath.
There have been some changes in northwest Kent:
- the Arriva 480 now runs via Bluewater between Dartford and Gravesend; the 490 no longer runs Bluewater to Gravesend.
- Arriva no longer runs the 477 between Dartford and Orpington. Instead, there is a 477 run by Kent Country (Go-Ahead) between Dartford and Orpington running hourly. (Confusingly, there is also another 477 between Dartford and Swanley, run by Go-Bus, which is half-hourly Mon-Sat.)
If you ever wanted to link Bromley and Orpington on the map, the 61 (Stagecoach), 208 (currently Go-Ahead, due to move to Stagecoach in July) and 358 (Go-Ahead) all link those places for TfL. Appreciate that might add clutter, though.
