Boris Island is an acceptable alternative to grabbing land from around Heathrow ,but if they build it I bet the air lobby will start quoting amazing figures for growth so as to double its size immediately its built.When the M40 was being planned a lobby group kept promoting the rail route as an alternative citing container trains ,more passenger and increased services to all points north,but the DFT swept their comments aside and ploughed on with motorway (which I do use to go north as it is quicker) sadly roads win all the time.Recently the noise level studies have been questioned and it seems as though a wider area will be affected by the trains so this another nail in its coffin.Whats wrong with losing a couple of trains per hour to provide a station in the Chilterns ,they are planning an amazing number per hour which will only a few will have more than a couple of hundred passengers on board.A service pattern of half a dozen each way per hour is more than satisfactory considering that businesses are discouraging unnecsary expenditure by execs.The DFT is clutching at straws in the execution of the project and is putting out some very dubious statements on the viability of this proposed line ,lets hope sense will prevail .
