Hubs Of All Kinds

Do we need a high speed train system (HS2) or should we spend less on a quality upgrade of the existing network? My inclination is that we need the latter. Do we need a new airport or will Heathwick suffice so long as Gatwick gets a second runway. A second runway at Gatwick has been mooted several times in the past only to have been turned down. What will make the result different if proposed again? I  must say I like Boris's proposal of a new hub airport in the Thames Estuary instead - see his article in today's Telegraph here. It has all the pizzazz to tickle the imagination a big project of this kind should generate and will attract a huge number of supporters. It will be something we can be proud of and can be built for the most part with private money and any which needs to be spent out of taxes can come from money saved from not building HS2. The rest of the money saved on not building HS2 can be used to ensure Dover carries out the building of its second terminal so that it can remain the busiest European  shipping hub rather than losing business to Calais. Dover and the Kent coast is generally run down and seedy and expanding the port will give a significant and much needed boost to the local economy. Who knows the powers that be may then be persuaded to upgrade the A21 to something approaching a proper road. How are ambulances going to get through the traffic to the new Pembury hospital without upgrading the road which often has 15/30 minute jams in that area? This is a question which frightens me.
