DLR have released details of the next phase of their Capacity Enhancement
project to enable 3 car trains to run on the Stratford and Beckton
routes. Interestingly, as well as extending the platforms of all stations
(except Custom House, Beckton Park and Cyprus which can already
accommodate 3 car trains, and Royal Victoria which will will see major
works as part of the Stratford International extension), Phase 2 also sees
a proposal to alter the Delta junction (where the Bank/Stratford lines
meet). The proposal sees a fly-under created for Bank/Lewisham services,
meaning that they avoid the junction. It will also mean that
Bank/Lewisham services will not be able to call at West India Quay as it
completely bypasses the station. The aim appears to be to create extra
capacity for new services from the Royal Docks to Canary Wharf as well as
more Stratford services.
