The most obvious bottleneck must be the single track between Pudding Mill and Bow Church, but the service on this branch is only every 10 minutes, so presumably it's not a pressing problem.
As the service on the DLR has increased, I've always felt that Canary Wharf might end up being a bottleneck, and as there's no realistic way of expanding the station, this will limit the amount of capacity to Lewisham and if any further extensions are built from there.
The remodeling of Tower Gateway seems a bit odd in the sense that it's been cut from having two terminating tracks to just one.
