Best. Diagram. Ever.

I attended a talk at the IET last night about the East London Line project. Looking, as we are, for a flat in Wapping or Rotherhithe, the future of that line is rather important to me :-)

The talk was rather technical but was made worthwhile by the inclusion of the best diagram in the history of the world. The presenter was attempting to explain how he has modelled the project and reasoned about all the stakeholders and interested parties. The diagram below shows the first stage of his decomposition. I'm not saying railway folk see things in black and white but you could easily be forgiven for thinking you're either with them or against them...
