What is going on with TfL Bus Stops?

This is the map returned by the TfL website when you search for Northlands Avenue.

(If anyone can provide the 5 digit SMS code for the stop which has the naptan code of 490020271E2 in the Countdown feed which doesn’t exist in Naptan’s data, I’d be grateful.


And here’s a search for Bromley Town Hall - How many doubles can you spot?

I’m really not sure what I’m meant to be taking from these maps. Too many stops? Duplication? A particularly nasty rash?

I can 71982 as the SMS code for 490020271E2 but that may well be out-of-date.

BTWE, what happened to the thread on QR codes at stops? Or was I dreaming it all in the heat?
