Stupid railway
The whole HS2 thing is very poorly planned and I would support it if there was any joined up thinking.
The first question is why it is not joined up to HS1 ? They keep telling us that HS2 will reduce short haul air travel but if you want to go to Paris or Brussels and you take the train you have to get yourself across London by Cab or the Tube........ Why bother take a flight!
The other thing is that if you join HS2 to HS1 the route the railway would have to take would be across the relatively flat ground north east of London and not through the Chiltern hills making the cost of construction lower, and not to put in a station if the track is going under EMA is nothing short of stupid.
