Interesting and excellent progress. We really can't have A & B platforms in a station which will have such an increase in passengers before the Olympic Games and even more during them. It really is about time the decision was taken to re-number all the platforms in a logical order. It shouldnlt have been too difficult to call the terminating DLR paltforms 18 & 19 instead of 4A and 4B.

We accept his logic and the matter has already been extensively discussed between the ODA and TfL, Network Rail, and the Train Operating Companies (TOCs).The key problem is that changes to platform numbers will mean that signalling controls will also need to be changed. This work would be very expensive, possibly costing millions of pounds per number change. Along with TfL, Network Rail and the TOCs, we agreed that it would be a better use of public money to wait until the signalling control system for this area is replaced, some time in the next 10 years. Introducing new platform numbers then could be achieved at marginal cost.As new platforms are built, we are using suffixes, such as ‘a’ or ‘b’ because they do not require such expensive changes and cost that changing the numbering would. During the Games there will be many extra staff and volunteers on hand to help spectators get to their platform. In addition, there is also no sequence of renumbering which would be automatically intuitive to someone unfamiliar with Stratford, given its unusual layout and wide combination of routes and operators. TfL has prepared a renumbering plan, which removes all suffixes, and will likely be implemented when the changes can be economically achieved.
