The plans, official or otherwise, for Crossrail 2, or Chelney to give its old nickname, have changed over and over for half a century. I can't help wondering though: Why did they drop Piccadilly Circus from the plans? It served the whole 'interchange with everything' rule perfectly. Did they ever consider a Jubilee line interchange between Piccadilly and Victoria? Pall Mall anyone? What the hell is the point in having it go all the way to Epsom? Instead of splashing out on an extension to New Southgate, why don't they just have it take over the Enfield Town services and have it dip under at Seven Sisters or something? Most of all - what was the blooming problem with the Epping-Wimbledon plan in the first place? That Essex Road interchange would have given great connectivity with the Northern City Line.
