Does anyone know if any information has been published about any rearrangement of bus services between Whitechapel and Dalston Junction? I have read elsewhere that the opening of Croydon Tramlink resulted in a major rearrangement of bus services throughout its catchment area, and the ELLX's catchment area is already well-served by many bus routes.
For Croydon, Tramlink opened up new links to Croydon town centre from both New Addington which had no rail links at all so this took most of the traffic from the very frequent 130 and Addington routes. From Elmers End the 54 was curtailed at Elmers End after opening of Tramlink. Most other routes were relatively unchanged IIRC.
I don't think there will be many changes to local routes when the ELL is opened just because of the areas the ELL serves and the Tram was always considered to be a direct replacement for local bus services where the ELL isn't. The fares structure will be LUL style too so many people will still use the cheaper buses.
