City and Brixton Railway   David  Whilst I utterly agree with you that there have been dozens of proposed but not constructed schemes there are only a handful of schemes which received royal assent over the years the only three I can think of are the CB the North West London and the North East Suburban Electric Railways  They surely count in a different class as legally they were allowed to be constructed and were only not because of poor finance  This is unlike say the more extended version of the Fleet Line stages  and  which from what I can tell ineveri even received royal assent and remained mere ideas  It is unfortunate that there is no seperate artical for tube proposals and hopefully someone will rectify this soon but Im convinced that the railways which were allowed to be built should be detailed  The information on these is also quite hard to come by  I intend to revert the artical for informations sake but feel free to contact me at albanianposse at hotmail dot co dot uk to discuss this more  I too am on DDs forum if youre a member so maybe see you there  Benedict
